Fabric accountability
In 2021 I started tracking my fabric in and out by month and it was a real eye opener. It took 3 months before I had a negative month- more fabric out than in. I made a goal of using backing fabrics from stash (of which I had plenty!) and limiting impulse buys (usually of even more backing fabric!).
Happy to say I ended 2021 with -28.0 yards and that is a great feeling.
Something about figuring out my monthly totals and seeing it written down helped me- it was a challenge to myself to keep that negative number growing.
It's just what worked for me, I'm posting this in case it helps someone else.
