I only have one quilt project going at one time, but I may have a knitting project or a crocheting project going at the same time as a quilt. I do have a money constraint, I can only buy with cash and I have a time constraint, I work full-time. My current fabric budget is small so I can only buy fabric and batting for one quilt project at a time which is fine by me. My stash is growing slowly with the extra yardage I buy for each quilt, but it will be a while before I could even think about making a quilt from my stash.
