I LOVE this subject! I started out buying just what I needed for a project (1981) For my daughters baby quilt. Now I like bolts, 6 yard pieces, 2 yard pieces, FQ's, 4 , 5, or 6 inch charms. I buy fabric in themes (roses, polka dots, cats, roosters n chickens, chicks, big floral, Native American, pansies, marbles, stars, stripes...). I have fabric in storage too and in my sewing room and in the back room. I LOVE fabric, the colors, the feel of it the bright ones and the muted...love it all.
The prices have gotten out of hand though. way out of hand. I find great deals on ebay or etsy at times. Rarely buy new anymore.
