Hi. I think your problem is the exact same one I've had.
Row 2: K 18, place marker, increase twice, place marker, knitt accross: 40 stitches
- so I knitted 18 stitches, tied a bow to mark my place, then I knitted 1 stitch as I was learning how to increase, then I did the two increasing stitches, then I tied another bow, but now I'm stuck -
After you do your increases you finish knitting the 20 stitches on the needle for a total of 40 stitches.
Your problem is all to familiar to me, both in knitting and crochet.
I hope what I wrote makes sense.
