I saw this on FB and I think it's a great idea. I hope that this link will work: https://www.facebook.com/lists/12839...type=1&theater.
In case some people can't see it then I'll post the picture with instructions below.
DIY pet bed! You will need: an old sweatshirt, bed pillow, polyfill or other stuffing, one lucky pet.
1. stuff sleeves and shoulder/collar area of sweatshirt (you might need to put in a few stitches to create a "pocket" in the body of the shirt.)
2. insert pillow through bottom of shirt.
3. stitch end of sleeves together
4. attach pillow "ring" to bed bottom with a few stitches.
