I cut fabric as I am making quilts, then if there is just a small amount left over, then I precut into strips or whatever. After seeing all those totally tubular quilts using 2 1/2" strips, I might just cut a strip to put into a shoe box along with other 2 1/2" strips. Other than that, I just cut what I need for a quilt. I precut strips before making my family reunion quilt this year, then discovered that I was off by 1/2" and was very ticked off at myself, I'm not precutting the whole quilt again like that.
