Yeti Cover

My husband and son are farmers.  Last year each received a 36 ounce Yeti as a gift.  My son wanted his covered so that it wouldn't get scratched from bouncing around in the tractor.  I made the Yeti covers from rip stop nylon and headliner foam-like fabric.  I quilted the two fabrics together, serged the side seam, and inset the bottom with the serger.  A little casing at the top and some 1/4 inch elastic and the cover is finished. They both like their Yeti cover.
