This is going to sound strange, but I have discovered that my Sweet Sixteen has absolutely no problem quilting through painted canvas, so I am going to go through my stored paintings and decide which ones to set aside for an art yard sale, which ones to keep for future gallery shows and which ones to think of as materials for quilted artwork. This will take me a good long while as I have been painting for more than 40 years, but it might eventually help declutter my studio space since that's where most of my paintings are stored... now to go find one thing to throw away, donate or sell today (other than the paintings).
