Arrange lace any way you like it, using a lot of pins to hold it in place.
I set that aside and started on the back of the bottoms. I pinned lace to the top edge right along the trim.
I measured down 3 inches from the top and marked with chalk, I did this on both sides.
Then I added another row of lace.
Then I measured the distance between and added a row of lace at 1.5"
There's the front of the bottoms.
Then flip over and start on the back. Do it the same as you did the front, tack first, remove pins, and sew on a zig zag stitch.
All done! Top and front.
Top and back.
Sorry about the pics, I don't have a dress form yet, and there is no way in hell that I am posting pictures of myself in a bikini on the interwebs.
