I know, I know, you really can't see the butterfly stitch in this picture, or any picture for that matter. The yarn I used made it difficult to photograph. But believe me, you can definitely see the butterfly stitch in person. I found the pattern here on ravelry. I tried to find a pattern for matching hand warmers using the same stitch. I couldn't find them anywhere! So, I had to come up with my own pattern. Here it is. It knits up really fast and the whole set only took 1 ball of yarn.
Butterfly Hand Warmers
1 skein of Patons Classic Wool Merino, dark gray mix colorway
size US 5 needles and size US 7 needles
yif = yarn in front
yib = yarn in back
s = slip (when slipping stitches, make sure to spread them out, so that your floats are even and don’t bunch up)
make butterfly = With your right needle pick up the 4 floats by inserting the needle under the floats from the bottom up, then insert the right needle into the next stitch on the left needle. Knit the stitch and the 4 floats together.
Cast on 40 stitches onto smaller needle. Work 2x2 rib (k2, p2) for 4 rows. Switch to larger sized needles. Knit in stockinette stitch for 2 inches, ending with wrong side row.
Rows 1, 3, 5, 7: [k5, yif, s5, yib] repeat to end.
Rows 2 (and all even rows for pattern sequence): purl.
Row 9: [k7, make butterfly, k2] repeat to end.
Rows 11, 13, 15, 17: [yif, s5, yib, k5] repeat to end.
Row 19: [k2, make butterfly, k7] repeat to end.
Repeat this sequence once more.
Work 2 rows of stockinette stitch (knit 1 row, purl 1 row). Switch to smaller sized needles. Work 2x2 rib (k2, p2) for 4 rows. Cast off, leaving a 8 inch tail. You will use this tail to sew up the sides. Put right sides together and sew about 2 inches down (this will be the top of the warmer). Leave about a 2-3 inch hole for your thumb. You can adjust the size of the hole to fit you. Sew up the rest of the warmer. Taa daa! All done! Now all you have to do is make another one and you are finished!
I hope you like this pattern. Let me know if I left anything out or if anything doesn't make sense. This is the first pattern that I made so I hope it works out well for you!
