I started doing the same thing. I had beds covered with fabrics; hall ways blocked, fabric every where! Then I had to buy more storage containers.
I am now being called a "HOARDER."
I was shocked just how much stash I have. What a surprise! Some of the fabric "I question how it got here!" Who would have ever created that pattern/color, etc.?
Amazing!
And I may never get it all back in the room. (that is the scary part)
