Fused 2 ideas here, but you can made a cool dog bed or this floor mat for kids (or big kids) just by sewing together pillow cases and inserting the pillows. It would be even more fun to mix and match the cases on the long floor mat. You can make with different sized pillowcases for larger mats. I'm thinking a King mat might be more comfy than my mattress.
