These sleeping mats are made from PLARN - that's a made-up word meaning plastic yarn. They are waterproof, cushioned, easy to carry, AND easys to make. Mats measure 3 ft. by 6ft. and take about 500 bags to make. You just cut the bags, knot them together and crochet the mat. Here's a video showing how. ENJOY.
