Well that sure is one addiction, I think maybe it is time to finish some of those quilts (bind them) and then offer them for sale. As they are all in piles around your home, what ever you get for them is more than you have now as sitting in piles around your home they are not producing anything but dust.
Failing that then I would suggest you start on step 1 -
sort into piles for removal from home, charity/gift giving/sale? and go from there, or you could go cold turkey :D
Good luck
