So I'm almost done with this purse but now I've come to the point where I need to cast off 11 stitches to make the hole for the handle. I cast off 11 stitches and I'm not sure how to continue knitting. I'm probably not understanding the directions but I'm not sure how to continue to knit without making the handle hole very small. Do I just start knitting again right after the 11th stitch I cast off? Any help would be appreciated!
