I had this idea to make a handbag with covers of romance novels for my sister for her birthday. I tried to collect ones with provocative titles. It made me laugh just picking this out from garage sales etc. Then I backed them with fusible web and fused them to this insipid pink calico.
Then I covered them with a medium weight vinyl sold for covering tablecloths, found in the fabric section.
This whole project was a bear to sew, maybe you will take this idea and make it easier? Backing it with fabric made it easier to slide through the feed dogs than vinyl alone would have been, but the vinyl stretches (surprise!) not fun--
