I use 2 yds each side for an avg adult, 3 yds for a man, 1 yd for a child. I cut a 6 inch square from each corner, and then cut my slits abt 2 inchs apart. all the way around. Bring the bottom piece up and around the top piece and tie it, do this 3 times to each slit. I have never used a kit. Hope this helps
