When I first started out, I bought for projects, then bought when something was on sale if I liked it. I have a fairly small stash and buy mostly on sale FQ's now. My tastes have changed over the years and I'm glad I didn't have tons of stuff I no longer liked. (did have some, but sold it on EBay). Too much tends to be overwhelming! As for yardage, I have way more vintage sheet yardage than new fabric. I used to think a quilt needed "at least 5 fabrics" or it would be boring...now it's closer to 50 fabrics or it's boring! I only have 1 true UFO a couple of WIP's and a small container of orphan blocks. I work best if I start and finish a project before moving on. I just finished cutting up all of my scraps into squares and strips and the 2" squares are going into a couple of granny square quilts. The scraps took up a medium clear box and weren't very inspiring...now that they are cut I know what to do with them.
