Well if you do use the lace (you can cut all the hair off it) actually you can even use any material atall (the idea here is not to let your scalp show so if you sew a fairly dark piece underneath your piece that way your scalp wont show and the thinning area isn't visable. Mightn't work in some cases depending on the site of the bald spots but will work I'd say in a great deal of areas. We are talking about concealing small bald areas in piece in certain areas not all over the piece.
