Hi! I am making knitted fingerless gloves for my friend using 2.25mm needles. The instructions were simple, broken rib knit for 2.5 inches, stockinette for .5 inches, then begin thumb gusset, once to a certain number of stitches, it said to put the 22 gusset stitches onto a stitch holder. Then I was to knit round for the hand and not knit the rest of the thumb yet. However when I went back for the rest of the thumb instructions it said to "reattach the yarn".
How do I go about reattaching the yarn? I'm completely lost here! Thank you!
