I made a feedsack lap quilt for my greatniece and it's always very nostalgic working with them. My SIL gave me about 20 large size ones. Treasures.
Yep, I did wear homemade feedsack undies, made by my Mom, when I was small. The older they got the softer they were.
BIG if you do decide to sell them, let us know. I might have a NEED for them. Something to help me coming down from completing the Texas Jane.
