I am not going to be of much help. I have, however, seen crochet used in quilts. I was wandering around the web and saw crocheted pieces used much like what is being discussed here. Unfortunately, where has blown my mind. It had to have something to do with contemporary quilting and quilters because that is what attracts me. I'm going to go back into my internet history and see if I can find any leads. In the meantime, please consider doing a wide search on the words crochet and quilting juxtaposed.
Please let me join with the quilters above and encourage you in your project. We'll all enjoy applauding.
