I hate bias tape!! Yuch, can't get it strait for the life of me. I have actually opened up the tape and sewn along one fold, then wrap it around and make the second stitch. It might be easier to just cut a facing. Mimic the outside edges all around and finish off the inside edge of the facing with serger, zig zag, fray check, or turn under and stitch it down. Love the doll clothes. I have 7 boys, one girl but she don't do dolls. I wonder why?
