These are also to sell in M's shop and just like the angels, someone else was sewing these and wasn't interested in continuing. There was no pattern, but it was really simple to make up. I just traced around the water bottle and then added 0.75". Of that, 0.5" was for the seam allowance and 0.25" was for "ease." The fleece is a little stretchy and it turned out to be a great fit.
The band across the front is a 2" wide overlap to allow the cover to come off the bottle. The buttons are decorative only.
Next up: a hanger pouch (still sewing for M's store...)
