Stretch elastic lace, White, 1/2 inch wide, elastic with gathered organza edge. Can use this to make stretchy baby headbands. To make this headband double-sided, place two strips with the elastic part on top of each other and sew down the middle.

(You can line up the elastic edges of 2 pieces, stitch them together, to create a cute lace that has a small gathered edge on both sides.)
