Dear Traci,
I don't think there is a 'wrong' way to put together a crazy quilt. That's why they're called 'CrazY'! Sounds like you have a jewel of a creation here and you've put a lot of 'yourself' into it. If most of your fabrics on the top are cottens I would definately layer in a mid-weight batting and then the backing. The backing shouldn't detract from all the work you have done on the front, so use a piece of allover print that will complement the colors you are using as side strips on the top, bottom and sides. As for quilting your piece, you will probably need to hand quilt it because you won't want to run over(with a machine) any of the special work you have done; the embroidery, the buttons, the beads, ribbons and trims you've intertwined into the piece, etc., Perhaps your best bet is a big round hoop to quilt it in, starting in the middle? and working your way out to the edges. First lay out the backing on a table, then the batting on top of that and then your quilt top on top of that. Pin with large safety pins every 12 inches or so to keep everything in place so it won't move around on you. Then lay it over the hoop, starting in the center and as I said, work your way out to each side. Quilt around the special sections you have, making them stand out. We would all love to see a picture of the top NOW or the finished quilt when you are done. Can't wait to see. I remember what it's like not having someone actually WITH you to help you go through the steps of finishing a quilt. Not having a lot of 'finishing' experience, I wish I could be there with you. Keep us posted and just keep asking questions. Nothing is too small to ask about. It's the small things that make the big finished product! Hope I've helped you.
