Ask yourself some questions we are "longarmers" would ask a customer when they bring a quilt for quilting:
1. What is this quilt going to be used for?
2. Do you want it for warmth or just a throw to wick off the cold i.e. at a football game?
3. What type of batting - 4 oz poly batting or all cotton or blend?
You will know what to do with your quilt when you stop and think about its future. I've made several and quilted several denim quilts for others - everyone single customer has put batting of some sort in the quilt. I also have two "camping" quilts made from my childrens clothes - they have batting and a cotton back. My only regret is not putting flannel on the back they would have been warmer when sitting outside at night at a campsite! Good luck. There have been many great responses.
