I purchase either whatever is left or I purchase by the bolt from a supplier that I have for wholesale. For me, I sell some of my work and people are always looking at what I have as well as people who do get something from me or see something I have made for our family will want the same fabric in thoer item, so to make sure that I will not be stuck iwth not being able to get anymore of the same fabric I just purcahse by the bolt to ensure that I have enough for a few projects.
I started out like most people, purchasing 1 or 2 yards at a time but as time went on and I become more addicted I just decided to get the entire bolt!
