I would start slow. Go into one room and organize that room in colour families. Once you see what you have in that room decide what you want to do with it. Do you have a giant mound of green and less of other colours? Take what you think you want from each colour pile and call a quilt guild. Tell them that that room will have fabric for $1.00 a meter until it's cleaned out. That will give you hopefully 1 empty room. Once that room is empty, put the fabric you saved onto mini bolts on shelves. Start going into the other rooms and selecting the fabrics to add to the colour shelves. Once you have that room full with your selected fabrics, again have a sale of the remaining fabric, offer for sale on QB or donate to charity shops in your area.I hope you can get it down to a comfortable level and the money you raise from fabric sales can go into the bank or be used to get your tops machine quilted. Good luck and we are pulling for you!
