The old quilt my mom made my DD had a sheet for the back and a blanket for the middle.

I would make sure and prewash all of the fabrics, since the sheet probably won't shrink :wink:

unless it's all cotton and brand new. sheets are not preshrunk. which is fine with me, since they stretch out each time they get used. eventually they would get too loose to stay on the corners of the mattress.
