One thing I have learned is that when I see a fabric I really, really like, I will try to buy 3-4 yds. of it because it may not be there when I go back to purchase more. One quilt teacher I had told us to buy it when we see a fabric we like because fabric has a shelf life, which can be very limited. There are exceptions to this, as there are certain fabric prints that have held on through many years of changing seasons and are usually available, but in my case the one I want will usually be the one that goes out of print.
