I do not buy material just to have a stash. Most of my stash is what is leftover from a project. I would just love to buy something if I see it but have to watch my budget close. It is amazing how some people have sooo much fabric in their possession and will never use it. To me that is wasteful. I guess alot depends on the type of quilting you do too. My hubby is very supportive of my quilting and often suggests when we go somewher to pick up some fabric. I have a hard time doing this. I feel that when I do have a project and need something he know I don't go overboard. You have to do what you feel is best for you.
