Using the E/3.5 mm crochet hook, work the top ribbing flat in rows using single crochet in the back loops only. After the ribbing fits comfortably around your hand, join it in the round and switch to the G/4 mm hook for the main arm warmer.
Top ribbing
Using the E/3.5 mm crochet hook:
Row 1: Ch 6, sc in the 2nd ch from the hook and in each remaining ch, turn (6 stitches)
For Rows 2–32, work in the back loops only.
Row 2: Ch 1, sc in each st in blo, turn (6 stitches)
Rows 3–32: Repeat Row 2 (6 stitches)
After Row 32, the ribbing should measure about 6.5 inches for the sample size. Wrap it around your hand to check the fit and add or remove rows if needed.
Do not fasten off.
Join the ribbing in the round, then switch to the G/4 mm crochet hook.
You are now ready to work the main arm warmer in the round.
Arm warmers
Using the G/4 mm crochet hook:
Rnd 1: Ch 2, make 1 dc in the side of each ribbing row, join (32 stitches)
Rnd 2: Ch 2, dc in each st, join (32 stitches)
Rnd 3: Ch 2, dc in each st, join (32 stitches)
Rnd 4: Ch 2, dc in each st, join (32 stitches)
Rnd 5: Ch 2, dc in 28 sts, ch 10, skip the last 4 sts, join (28 stitches + 10 chains)
If your stitch count is different, dc until 4 sts remain before making the ch-10 thumb opening.
Rnd 6: Ch 2, dc in each st and each ch, join (38 stitches)
Rnd 7: Ch 2, dc in 28 sts, dc2tog, dc in 2 sts, dc2tog, dc in 2 sts, dc2tog, join (35 stitches)
If your stitch count is different, dc until 10 sts remain before beginning the decreases.
Rnd 8: Ch 2, dc in 28 sts, dc in 1 st, dc2tog, dc in 1 st, dc2tog, dc in 1 st, join (33 stitches)
If your stitch count is different, dc until 7 sts remain before beginning the decreases.
Rnd 9: Ch 2, dc in each st, join (33 stitches)
Rnds 10–29: Repeat Round 9 (33 stitches)
Fasten off.
Bottom ribbing
Using the E/3.5 mm crochet hook, work the bottom ribbing separately in rows.
Row 1: Ch 6, sc in the 2nd ch from the hook and in each remaining ch, turn (6 stitches)
For Rows 2–33, work in the back loops only.
Row 2: Ch 1, sc in each st in blo, turn (6 stitches)
Rows 3–33: Repeat Row 2 (6 stitches)
The number of ribbing rows should match the number of stitches around the arm warmer. For example, if you have 33 stitches at the end of Round 29, work 33 rows of ribbing.
Assembly
Sew the bottom ribbing to the arm warmer, matching one ribbing row to each stitch around the arm warmer.
Sew the short ends of the top ribbing together, then sew the short ends of the bottom ribbing together.
Finishing your crochet arm warmers
Once the ribbing is attached and the seams are sewn, weave in all remaining ends. Your crochet arm warmers are ready to wear.
