I downsized to a 2 bedroom apt. 2 years ago. I use the master bedroom as my sewing room so I didn't have to give up a lot of my quilting stuff. I'm now shopping out of my stash for new quilts. I's amazing how much I can use. DD is also a quilter and we share. She will receive whatever I have (there'll still be a lot of it).
I've collected Santas and Christmas decorations for years and gave away/donated most of them. I'm sad at Christmas, missing them. So be careful of giving away items like that which you may miss. I was surprised how much I missed some of them.
