My fabric stash has doubled since before the Halloween costume projects started. I'm not a confident sewer, so I buy more than the amount of fabric I need just in case I screw up. Lucky for me, the fleece was on sale at JoAnne's and I could afford to do that this time. Now I've got enough left over for a few more Halloween costumes. I'll have to convince the boys to be something green, red or yellow next year.
I packed all the fabric away into two cardboard boxes and stashed it away in the utility room. Ultimately, I want to get a plastic Rubbermaid container for the fabric, since I think it's unprotected from mice as it is.
