I love being able to incorporate stitching into these pieces to give them an extra layer of texture, which is something I can't do on my regular stretched canvases because of the wood bars (or if I do, I do it by hand with a giant sewing needle and a hammer to get through the 5+ layers of paper, glue, paint etc. on every painting.)
My new (to me) sewing machine, a 1968 Bernina Minimatic, is thanks to my mom, who used it for 45 years before sending it my way. Despite some hard times and a stubborn teenage attitude, she's showered me with every art supply I asked for over 25 years and last month shipped this 20 pound vintage machine from Seattle to Boston to ensure I didn't end up with "that new plastic crap." And this thing is solid.
Luckily I'm okay at sewing thanks to a few years as costume director and stage manager and other awesomely nerdly things in my high school drama club so it hasn't been too figure out how to stitch plastic and paper.
