I need lots of fabric when I start to quilt. I pull out 100 different pieces sometimes. I don't think I am a hoarder. I did stack up for years for when hubby retired I wouldn't need anything, and that was a good thing.
I don't buy fabric, I am not even tempted. We still live in our three bedroom house and I have one closet with three bookcases up to ceiling stacked with fabric, sorted by colors. Two dressers with all the drawers full, and one 8x5 cabinet with shelves, full also. I can see all my fabric at a glance, so it's easy for me to start a project. I also have a couple of bins, one with Christmas fabric that I plan to donate and one with decorator scraps that I use for bags and things.
