I think that as long as it is organized and you KNOW where your fabric is then it is not hoarding..just saying...Here is my story, tomorrow I am giving a class on making a 4-patch lap quilt..I sent the pattern and supply like including fabric needs. i suggested that if any of them couldn't get out to buy the fabric i could supply a kit for a fee..He he he they all want a kit so I spent all day yesterday putting together 8 Kits.. including backing, batting and binding.. all from my stash!!! I will teach them to tie the comforter.
It's what you do with what you have. I bought it when I was working, now that I am retired I have to have a good reason to spend on fabric and its mostly to finish a project .
