Doggy Coat How-To
1. Cut fabric into a 14-by-11-inch rectangle and two 1 1/2-inch-wide straps, 13 and 14 inches long (for other sizes, test with muslin or newspaper); round the corners.
2. Drape over dog. Mark where buttons will hold the straps, across the lower neck and behind the front legs.
3. Sew buttons onto main piece; cut slits in straps. (As dog grows, make longer straps.)

When I needed to make something for a Humane Society benefit, I didn't want to have to go buy supplies. So I used a piece of medium weight jaquard upholstry fabric that I already had and made this (in the size described). Of course had to hem it, and tubed the straps. Made a small rosette to add just behind the neck area to dress it up. (My first time making a rosette! Easier than I thought!)
