We all start and stop at different points in our stash building. I joined the moratorium years ago for full priced fabrics, and even sale fabrics, but I gave myself a thrift shop exemption... I currently have more fabric than I want and am working at reduction in various ways and being very conscious of when I do buy but I accept that some fabric does come into my life from time to time.
What I really need to work on right now is getting the long arm I bought about 2 years ago now set up. Ok, I had severe vision issues for a full year and couldn't but I've been able for the last year. Once I can get some of my donation tops quilted down and set free to face the world, I will have space for new tops which will come from old stash... that's the multi-year plan anyway.
Until then, I'm just doing my best not to tempt myself and only buy when I have to. Right now I'm not doing so much sewing so I'm doing zero buying.
