The first time I saw a pillow mattress on Pinterest, I knew I wanted to make one. Many of them are made by sewing four or five pillowcases together and supposedly taken minutes. I really couldn't find any flannel pillowcases that would do for a two year old, plus I couldn't find just flannel pillowcases sold separately. They were all sold as part of a sheet set. So a trip to the Hancock Fabric shop it was.
I tried following several different tutorials and went through several trial and tribulations, but in the end it came together just like I envisioned. I did include a fabric pocket on the open end to allow the pillow to be tucked in securely. The pillows I purchased were quite fluffy, and even though I had made the pocket and it worked perfectly, I also added heavy duty snaps to keep the ends closed.
