@annieeg, enjoy the excel spreadsheet. I love it and this is the second year I have used it.
I do have a game plan when using it. If I buy fabrics and use them up, I don't record them as purchased and do not count them in stash used. If I stash it for longer than 30 days I record it as purchased and then when I use it.
I set my goal (which I am not meeting), put Multiplier at 100, and the units as meters. What i am most interested in is how much I have bought and stashed and how much I have used out of the stash. I do include craft weight interfacing, fusible fleece and some other interfacing I've had in the stash for a long time. It has helped me focus on using them up and I know I will have to buy more as time goes on. I'm okay with that as my goal was to use up what I have on hand.
When this spreadsheet was posted, a lot of ladies decided to measure their stash and record it. I chose not to. It is on the shelves for me to see and the goal, for me, was to sew it up and buy as little as possible. I wasn't going to use precious time to measure the fabric I had. I measure it when I use it up. And for me, that works.
Another goal I set this year was to sew up the scraps of fabric left over from projects rather than put them back into the stash. I'm at about 65% of meeting that goal. My biggest reasons are getting tired of sewing the fabric or I need to buy more fabric to finish the project.
In December I will look at my totals and see what I will change for 2020. I may not record what I've put into the stash and record every meter I sew whether it is from the stash or new bought. I may use the purchased column for new bought fabric so I can track all the incoming fabric. These are ideas floating around in my head. What works for me, may not work for other people. And that is great.
