I have made many potholders that are from left over blocks and QYG with strips. for QYG I use 2 1/2 in binding and have not had a problem. if I am using left over blocks I birth them. Found this works good if they are big enough 8 inches usually works well. For binding I found a site (sorry can't find it again) where she pinned where the two ends came together then cut the binding leaving half inch lap over and sewed at the pin mark. Works great. On 8 1/2 inch length I did have to begin sewing at about 1 1/2 inch from the corner, make my turned corner, go around and then stop about 1 1/2 " from last corner. Need to back stitch both start and stop. This gave me enough room to sew ends together without resistance. I found this works best for me. Hope I made this understandable and will work for you as well.
