I'm in the process of making rugs this way out of upholstery fabric. I've had samples sitting around for years and thought a long time ago I'd make rugs out of them. So far so good. I've cut strips of fabric and using batting that I no longer like in my quilts. It took some time to cut everything but it's all working.
You could use the small roll of 20 strips. It would just make a smaller rug. It's been fun. Just take your time and go slow with it.
