Here's something different! This is a length of lace, which is 50cm long, but shaped at either side.
The picture shows the lace folded in half, and hopefully you can see the back is slightly wider than the front, and the tops (waist) considerably wider than the bottom (gusset).

The shaping suggests this is intended to make knickers! The lace stretches the usual way, so this means when you make it into knickers it needs some stretch sides or you'll not get into them! You could make these tanga style or overlay onto a stretchy mesh knicker base. Have fun!!!
