i hope you have stopped adding to it
start using what you have- shop in your own (store)
try organizing according to theme/design instead of colors- that might help-
as in-
put together everything that would work well for baby quilts,
girl/kids quilts, boy/kids quilts
reproductions
blenders
florals
landscapes--- get my drift?
as you sort start in one area-don't worry about what is in the next room- only worry about what is right in front of you
as you get going you may come across stacks that you figure you will never ever use- set those aside- then snap pics of them- measure them and post them in the classifieds- people will buy them from you
but first is not adding to what you have- no matter how much you love it! write down your goals---do you want to get down to one room? do you only want to organize? decide exactly what you want to accomplish---and write it down---then work toward that goal- if you feel the urge to 'shop' -browse on line shops---looking- even adding to a cart---then empty that cart and move on---don't actually buy anything (window shop) until you have reached your goals.
