My son received a new Yeti bottle for Father's Day. He was so pleased with it he did not want to get it scratched and wanted a cover for it. Yesterday I made a quick cover for it from camo fleece and he really liked that. But my DIL wanted a more substantial cover so she purchased some headliner and rip stop nylon. She is not much of a stitcher but she did a great job making the "quilted" sandwich using my great Bernina tools. Then I made a tube the correct diameter and serged away. I cut a circle for the bottom and serged it together. A little tube at the top with some elastic made the perfect Yeti accessory.
