With two quilts to finish and post by December 2nd. I turned to the sales at JoAnn's on fleece. The flimsies were done, just needed time to sandwich and sew. Oh my, I started at 8:30 this morning and finished the second one at 2:30 this afternoon.
Granted, I did not do fancy quilting, just loop de loop. I used Heat N Bond spray to hold them together, no pinning. I was careful not to stretch the backing too taut. Stitched the binding by machine. Fast and easy for anyone needing to get many done before Christmas.

Thanks for this tip!

I’ve used fleece several times for quilt backing. I do not do batting when I use fleece. It makes for a soft, fluid quilt that is super snuggly.

You are right, I did not use batting. What thrilled me so much about this is, the sandwich is the part that I stumble on when quilting. Lots of flimsies waiting to be finished.

Thanks for the tip, Toverly. I have a bunch of fleece I don't remember what I had it mind when I bought it. Now I know what I can do.

Can you do intricate quilting with a fleece backing/batting?
Or is it best to keep the quilting simple and not too close together?

I like that description - soft, fluid. I'm not a fan of intricate quilting, probably because I don't make wall hangings. I like my bedding to drape around my body so I can snuggle into it. I appreciate intricate, fancy quilting lines and how quilting can be used to enhance a pattern. My quilting isn't in that category.
Yet.

Because I was in a hurry, I did a simple loop de loop. I don't know about intricate quilting, that might take away the softness.

I started using a good quality fleece for my quilts several years ago. As I quilt all my own quilts on my Janome it is so much easier not to have to get 3 layers set up and ready to be quilted. I love using it.

I use fleece (no batting) on kids quilts. I usually tie them with embroidery thread and do a facing instead of binding. Once I put a diagonal plaid fleece on the back and followed the diagonal lines with my machine to quilt it. I think that was my favorite one.
