Just like you, I used to buy yarn for knitting. Then I decided to move from Massachusetts to Florida. Between my yarn and my books, reducing what I would take with me was painful. Now that I am quilting, I allow myself to buy a few precut fabrics in colors I know I'll always use to have on hand for trying out ideas. I only buy larger amounts for a specific project. Now if I could only keep myself from buying books, I might be able to declutter my condo. Living in a condo also keeps me from buying that extra fabric.
