Sometimes i plan a quilt from the border fabric, sometimes i buy all the fabric for the quilt at one time. A few times, the fabric i picked for the border doesnt do the quilt justice and i have to use something else. Sometimes i dont have enough of the border fabric, so i will put something in the corners or piece the border. I've learned to be flexible- sometimes a better idea comes along than what my poor uncreative mind comes up with.
