Use the high loft batting to stuff a quilt or a pet bed. I'm behind on quilting tops, and I have a long arm on a frame.
For many of them, I just have to be in the mood to quilt them. For a few of them, the mood hasn't hit me for 4 or 5 years!
Organize fabric one laundry basket full at a time. donate or sell fabrics that no longer appeal to you. Mark the length of fabric on the fabrics you decide to keep.
I recently set a rule for my personal fabric collection: if I haven't used a fabric in 5 years, it gets donated for charity quilts. It's hard to let go of some of them, but I have to 'thin the herd' because I know that I will never use all of it and I have no room for new fabrics!
Please note: I think the only reason I quilt is so I have an excuse to buy fabric!
