I made this recently for my grandson's birthday, I wanted it simple and washable. Sorry, I didn't take specific measurements. The fabric was bought at Hobby Lobby and washed and dried before I started sewing.
To make the pillow I made a square that was appoximately third the size of the quilt by width. The size I experimented with until I got the size that work. I sewed the sides but left both ends open.
To make it into the pillow, fold the quilt 1/3 over and the other 1/3 over.
Start at opposite end of the pillow top and fold over twice.
I will be posting this to these blog parties:
