I grew up around sewing and made most of my clothes and my daughter's. When she was 2 and she was ready to move from the crib to a big girl bed, I made her a quilt to make the transition easier. She is now 37 and still has the quilt even though its warn and faded, she still loves it.
I did everything wrong. I used 5/8 inch seam allowances and I pillowcased a twin size quilt so no binding and then machine quilted it. It turned out fine and looked pretty good inspite of my "mistakes."
