Quit top for my student teacher

I have a student teacher this semester- Sarah.  She's awesome and will make a good teacher ( that is if she still decides to teach after dealing with some of my ---how shall I say--- more challenging  students- and we have many).  She has about a month left and I thought I'd make her a quilt as a present when she's done student teaching.  I've been collecting vintage sheets now for a while and since Sarah's really girl, I thought I might make her a cute little quilt from my vintage sheet collection.  I originally just cut up a bunch of 3 inch squares and wasn't sure what I was going to do, but I think it came out really cute.  Now I just have to pick a sheet for the back and quilt it.
