Depends on where you want your loop to hang it...the corner or the middle of the side. Put your hook thru the first loop then reach to the next loop and pull it thru the first loop. Catch the next loop and pull it thru the second loop....and so on around the frame. Your instruction sheet should give you ideas for finishing it.This is one that was made at school and the teacher crocheted the edges.
maybe I can just send this unfinished one to school with him and she can crochet the edges for me too.View attachment 1996201 View attachment 1996202
