Today I bought some fabric at Joanne's and it just screams out to be a one piece wonder. All I'll have to do is plop it down on batting and backing, got that there too, all 40 percent off. (Not the batting) And then I'll stitch in the ditch on all the squares there.
Something like that would fit you nicely, and get you started quilting right soon. I'm cheating because I want to make at least 4 premie quilts for the hospital I used to volunteer with so long.
This will be easy to do, probably what will take most time is the binding, haven't decided on that yet.
