As a quilter and a realtor, I can understand both sides. When you get ready to market your house, you will want to keep your stash as organized as possible. There's a big difference between organized and clutter. I would suggest, that as long as you are organized and can make it possible after receiving an offer on your home so if need be the buyer wants an inspection conducted. As long as they are able to inspect without interference, you should have no problem. And if you keep it organized, I'm sure it will only add more color and dimension to the home. It may not be on market long. So be prepared. Also keep in mind when you speak with your realtor, you may want time after closing and funding before the buyer takes possession. Would give you a little more time to pack and move. Good Luck!
