I have many of my Grandmother's quilts that she made out of double knit. I've had to put new bottoms on them but I doubt the tops will ever wear out. When I put the new bottoms on I've found old old quilts inside, sometimes quilted blankets. Just whatever she had.
Somebody always got a quilt for Christmas, others got one for their birthday.
In her later days when she made the double knit she knotted them all.
When she was getting less and less mobile, I used to stretch and pin them to the floor for her, per her instructions. She would then have me start the knotting.
I have to credit her for inspiring me to make handemade gifts for my family
