That is adorable!! I love the doll blankets too!! The fabric for the first one--with the tools--was a great idea. I'm sorry it was so frustrating for you. :(
For 15 years I sewed with a machine that didn't have anything to help with a 1/4" seam--I struggled. The best I could do it use a magnet to mark it. But the magnet had to come off for quilting, so it was always moved. My new machine helps me nail that 1/4" mark--and what a difference it makes.
Good luck! And happy quilting!! You pick wonderful colors. :D
