well make large nine patch blocks, it will all be easier that way. Good luck.

I would recommend flannel for the backing. It will be heavy but do-able. Fleece required special attention as it is more stretchy than regular fabric. You might have some trouble quilting.

Thanks everyone for your insight. I said I was going to do flannel and maybe denim on the back. My dad is thin as a pin (never been very big) so I am going to do just as it has been suggested and what I had thought was best.

I made a denim quilt, I embroidered on the denim patches i the middle of my Dresden plates and had flannel patches, backed with flannel. OMG it was so heavy I almost couldn't lift it. I had to take it to the laundry mat to wash before I gave it, using the industrial washer. It was almost to much for that!! Never realized how heavy that combo was!!!

My worry is that with that heavy a quilt your dad wouldn't be able to move under the quilt.

Why not use wool or quilters dream poly? They are very worm and light. P

Just a question. I know fleece is made from synthetic material. Is flannel made from cotton or from synthetic material? I never thought about the warmth of fleece but I love the light weight of it, especially when you sleep on your back.

I made my Mom a crazy quilt top (lots of seams) she put a velcro blanket on the back and tied it. It was so heavy she could not even sleep under it.

I made a quilt out of denim, homespun and one layer of batting. It was very heavy and difficult to move under. It was a quilt as you go pattern or I would not have been able to wrestle it through my machine. I'm afraid by the time you get all those layers together you will have a quilt that will weigh so much it won't be comfortable to be under.

Flannel can be wool, cotton, or synthetic, but quilters usually use cotton flannel.
