Finally, September!

Rejoice, the -ber months are finally upon us! Indeed, September is the promise of fall and my favorite time of year. For instance, football is back on television, there’s a hint of color on the trees and it’s pumpkin-everything season. And best of all, it’s time to bring out the sweaters and cardigans!

Moreover, I am thrilled to release the pattern for the Sylvan Sweater, my first cool-weather project of the year! The word “sylvan” is Latin for wood or forest and perfectly captures the sage green color of my finished sweater. It speaks of nature and an earthy, wild feeling that connects with the changes that fall brings. This beginner-friendly lightweight crochet sweater features soft DK weight yarn, an open stitch combination, and 3/4 length sleeves for the perfect sweater to transition into cold weather.

Design Inspiration and Features – The Sylvan Sweater

I wanted a lightweight crochet sweater that was comfortable as well as stylish and easy fitting. The Sylvan Sweater is crocheted starting from the bottom of the panels and features a squishy ribbing for the hemline. The main body of the sweater is crocheted directly onto the ends of the ribbing rows and the front panel is finished with shaping rows to create a scooped neckline. 3/4 length sleeves are crocheted separately and then seamed onto the armholes and are meant to be open and roomy. The sweater’s fit is meant to be relaxed and comfortable, and in similar fashion, the open stitches keep this lightweight crochet sweater from being too heavy or stiff. I love the way my sweater sits right across my hips without being too snug or gapping in the wrong places.

The Perfect Yarn for a Lightweight Crochet Sweater!

My first time using Superwash Merino by Lion Brand Yarn did not disappoint! Superwash Merino is a favorite for indie yarn dyers because it holds dye really well and is easy to care for. The fibers are treated for a smooth finish and create a much softer and easier-wearing yarn than 100% wool. This luxury DK weight fiber has a soft and squishy hand feel but is affordable and readily available – and machine washable! And the drape on my finished lightweight crochet sweater is incredible! My finished sweater hugs me in all the right places and is the perfect garment for transitioning through the changing seasons. What’s more, as a perpetually hot-natured person, I appreciate a garment that doesn’t feel like it’s suffocating me. With this in mind, Superwash Merino by Lion Brand comes in a variety of gorgeous colors as well!

Crocheting my own sweaters, cardigans and other cold-weather wearables is undeniably one of the best things about being a crochet designer. The pride and sense of accomplishment I feel when I wear a sweater that not only did I make, but created from an idea in my head, is so satisfying! Without a doubt, it lights me up inside to be able to create something that other makers will want to make and wear as well. I hope you enjoy making the Sylvan Sweater and that it becomes a staple of your fall wardrobe!

 *FITS CHEST refers to the measurement of the intended wearer.  FINISHED CHEST refers to the measurements of the finished garment. 

*This lightweight crochet sweater is intended to have a relaxed, comfortable fit with 4-6 inches of positive ease in the main panels of the sweater.  In addition, the sweater can be customized in the length of the sweater panels and the sleeves.

 The sweater pictured is a size Large and the model is 5’4” with a 40” bust. 

GAUGE:          

  • 19 stitches X 16 rows (8 hdc rows/8 ch3-sp rows) = 4 inches
  • Ribbing (half double crochet in the back loop only)  14 rows = 4 inches

It is recommended to work a gauge swatch that mirrors the pattern instructions, from the ribbing up. 

GAUGE SWATCH:

Ribbing is crocheted first, and then is turned horizontally to work hdc sts across the ends of the rows to continue the swatch from the bottom up. 

Ribbing:  Ch 11

Row 1:  Hdc in 2nd ch from hook and in each ch across.  Turn.  (10 hdc sts)

Row 2:  Ch 1 (does not count as a st), hdc in both loops in first st.  Hdc BLO in next st and in each st across, ending with hdc in both loops of last st.  Turn. (10 hdc sts)

Rows 3 – 24:  Repeat Row 2.

Turn the ribbing horizontally to work stitches into the ends of the rows.  Work approximately 4 hdc stitches for every 3 ribbing rows:

Row 1:  Ch 2 (does not count as a st), hdc across the ends of the ribbing row ends according to the instructions above. Turn.  (32 hdc sts)

Row 2 (RS):  Ch 2, sc in first st.  *Ch 3, sk next two sts, sc in next st.*  Repeat from * to * across until one st remain.  Sc in last st.  Turn.  (10 ch-sp plus 12 sc = 32)

Row 3 (WS):  Ch 2, sk first st, hdc in next st.  3 hdc in each ch3-sp across ending with hdc in last st.  Turn.  (32 hdc sts)

Rows 4 – 21:  Repeat Rows 2 and 3.  Measure ribbing and main stitch pattern WITHIN your swatch to determine gauge.

OVERALL PATTERN NOTES:

  • Pattern is written in smallest size with larger sizes following in parentheses:  XS (S, M, L, XL) (2X, 3X, 4X, 5X). 
  • This lightweight crochet sweater is worked in two panels for the main body that are then seamed together at the shoulders and sides.  Work the front panel as the back panel except for the last few shaping rows for the scooped neck opening. 
  • Ribbing is crocheted first at the bottom hems of the panels and then turned horizontally to work half double crochet stitches across the ends of the rows.  Work the panels from the bottom ribbing up. 
  • Sleeves are ¾ length and are worked separately from the cuff and seamed onto the armholes.  There are no increase/decrease rows for the sleeves, they are the same width from the cuff to the armhole.  Finish the sleeves with simple detailing to slightly cinch in the cuffs. 
  • Ch 2 and Ch 1 do NOT count as stitches.     
  • If you are adding length to your lightweight crochet sweater, end with a Row 3 repeat and make sure to adjust the front panel accordingly.  For example, if you are working the size L and want to add 6 rows, the back panel will now end at row 79.  Neckline shaping for the front panel for size L begins 10 rows less than the back panel; in order to account for the front panel shaping for that size, you will need to end your front panel at row 69 before beginning your neckline shaping rows. 
  • If you are adding length to the sleeves, end with a Row 3 repeat.    

Special Stitches

Single Crochet Two Together (sc2tog):  Insert hook into intended stitch, YO and pull up a loop (two loops on the hook).  Insert hook into next stitch, YO and pull up a loop (three loops on the hook).  YO and pull through all three loops. 

MAIN PANELS OF THE SWEATER

Notes:  Ribbing is crocheted first, and then is turned horizontally to work hdc sts across the ends of the rows to continue the panels from the bottom up. 

Back Panel

RIBBING

Foundation Row:  Ch 11. 

Row 1:  Hdc in 3rd ch from hook and each across.  Turn.  (10 hdc sts)

SLEEVES (make 2)

Sleeves are worked flat in turned rows from the forearm to the shoulder and rows do not increase or decrease.  The long yarn tail is used to seam the sleeves onto the armholes and down the inside of the sleeve to the cuffs. 

Foundation Row:  Ch 57 (63, 69, 72, 78) (81 , 87, 90, 96)

Row 1:  Hdc in 2nd ch from hook and in each ch across.  Turn.  [56 (62, 68, 71, 77) (80, 86, 89, 95) hdc sts]

Row 2 (RS):  Ch 2, sc in first st.  *Ch 3, sk next two sts, sc in next st.*  Repeat from * to * across until one st remains.  Sc in last st.  Turn.  [18 (20, 22, 23, 25) (26, 28, 29, 31) ch-sp]

Row 3 (WS):  Ch 2, sk first st, hdc in next st.  3 hdc in each ch3-sp across, ending with hdc in last st.  Turn.  [56 (62, 68, 71, 77) (80, 86, 89, 95) hdc sts]

Rows 4 – 45 (47, 51, 51, 45) (45, 45, 41, 41):  Repeat Rows 2 and 3 and fasten sleeve off, leaving a yarn tail twice the length of the entire armhole and down the inside of the sleeve to the cuff.    

SEAMING THE PANELS AND SLEEVES

PANELS

Lay the back panel flat with the wrong side facing up and position the front panel on top with the right side facing up.  You will be seaming the sweater together with the right sides facing out.  Make sure to line up the stitches across the top of the sweater in order to match the hdc clusters to each other; secure with stitch markers.  Using the yarn tails, seam the shoulders.  I used the mattress stitch to seam my lightweight crochet sweater because this seaming method creates a smooth join. 

Line up the sides of the sweater and pin, leaving 6 (6.5, 7, 7.5, 8) (8.5, 9, 9.5, 10) inches for the armholes.  Make sure the hdc clusters are in line with each other and rows are lined up with each other from the back panel to the front panel.   Join yarn at the armpits and seam down the sides of the sweater, ending where the ribbed cuff begins.  Again, I used the mattress stitch to seam my sweater as this creates a smooth join. 

SLEEVES

Repeat for both sleeves:

Lay the sleeves flat with WS facing up and fold the sleeve over to line up the rows.  RS is now facing up; pin the sleeve together down the inner seam to hold in place, making sure to line up the hdc cluster rows.  Attach the sleeve to the armhole with stitch markers.    

Using the long yarn tail and beginning at the armpit, seam the sleeves to the armhole using the mattress seam, working your way back to the armpit.  From the armpit, continue seaming down the inside of the sleeve to the cuffs and fasten off. 

Photo References – Seaming

COLLAR EDGING

Edging is added to the neckline in rounds that do not turn.  Overall stitch count is not important as long as stitches are crocheted evenly so the first round does not pucker or curl. 

With the sweater lying flat and RS facing up, join yarn on the right side facing you where the last shaping row of the front panel meets the shoulder seam.  Working along the front panel: 

Round 1:  Ch 1, sc into same st as join and PM into this st.  Sc evenly into ends of shaping rows, across front panel sts, into ends of shaping rows on other side and across back panel sts until marked st is reached.  Sc into marked st and move marker up into this st.  DO NOT TURN. 

Round 2:  Sc in each st around to marked st.  Sl st into marked st and move marker up into this st.  DO NOT TURN. 

Round 3:  Sl st BLO in each st around to marked st.  Sl st into marked st and fasten off. 

Photo References – Collar

SLEEVE EDGING DETAILS

Crochet edging directly onto the ends of the sleeves in rounds that do not turn.  Crochet the first round into the foundation chain of the sleeve; the directions below apply as for both sleeves. 

**You should have the same number of stitches as for the flat turned rows of the sleeves, but depending on how you join yarn you may have one or two more or less stitches; this is not crucial as long as the rounds worked do not pucker or curl which would indicate too many or too few stitches.

With the sweater facing RS up, join yarn at the end of the sleeve at the inner seam.  Working along the side of the cuff that is facing you: 

Round 1:  Ch 1, sc in the same st as join and PM in this stitch.  Sc into each chain around back to marked stitch.  DO NOT TURN. 

Round 2:  Sc in marked st and move marker up to this st.  Sc in next 3 sts, sc2tog in next 2 sts.  *Sc in next 4 sts, sc2tog in next 2 sts.*  Repeat from * to * back to marked st.  If there are not enough sts to work a repeat at the end, sc in each st remaining.  DO NOT TURN. 

Round 3:  Sc in both loops of marked st and move marker up to this st.  Sc BLO in each st around back to marked st, sl st in both loops of marked st.  Fasten off.
