I had a bedroom renovated 2 years ago, to convert into a craft/sewing room. I just have too much crafts (I'm also a scrapbooker!) and sewing stuff lying around and needed a more organised space. Out of this, I custom made a cabinet just for my fabrics. I'm fond of buying FQs, and I sort the loose ones according to colours neatly in my cabinet. Those FQs and yardages which I buy as a set/collection get stacked together, as I like to work with fabrics from similar collections, so they mix and match well together.
I'm not even sure why I keep buying fabrics when I don't have much time to quilt nowadays. I only see the volume increase, but never decrease. LOL.
