Why not just use fleece on the back! I never use batting anymore. It is too expensive, and I prefer to have the warmth of the fleece for a cuddly blanket. Just be sure to have the selvedges on the sides.

I didn't put batting in mine...it would have been way too heavy.....but i did "quilt" them around the logos and SID. Have to keep the front and back from separating somehow, right??

I quilted a dresden plate table topper without batting and I found it very difficult. Swore I would never do it again. W&N and W&W are very thin batting and what i would use if I ever do another.

A quilt without batting is often referred to as a "summer quilt" or a "counterpane." They are commonly made, especially in areas where it is hot and humid. I've made two. One I machine stitched a meander all over it. The other I just machine stitched along both sides of the lines of stitching on the top (like Tom W described). I wash in my washing machine without problems. If it is well stabilized, it should not be a problem. But if it is going to get heavy use, I'd be afraid that the tshirt fabric would start stretching and getting wonky over time and would put a thin batting inside.

I, also, have an old quilt top to "finish" for a relative. The quilt has been in a bag or closet for MANY years. It also smells, and it has some places to fix... a few seams have come undone. I really don't want to wash it until it is fixed, sandwiched, and quilted. Then I will wash it on gentle. It's not a smoky smell, it's an old, musty smell, and I can deal with that while working on it.

Like Jingle, I once made a tablecloth without batting. Never again!

Last night I finished a t-shirt quilt for my granddaughter. I stabilized it with fusible pellon and backed it with 108" wide flannel. Nothing else in between. Stitched 1/4" or so... inside some of the squares, as they were all different sizes. It's plenty heavy right now, can't imagine batting inside it. I'm happy with the results.

I have made 1 quilt with out batting and 1 using flannel. I did not like either. No batting wrinkles alot since there is nothing to hold the shape. Flannel- it is just as heavy/warm as with Hobbs 80/20 batting that I usually use and it turned out to be way more expensive. I use Hobbs 80/20 that I get at Hobby Lobby- queen size- $20 -40% coupon = $12. Flannel $3(on sale at Joann) x 6yds=$18.

thrift shop for flannel
 

I agree. I can get great flannel blankets or sheets for under $3 that work wonderfully as batting - and they are well washed so all the shrinking is gone.

Pin basting and glue basting would be double work with no difference in results. Glue basting eliminates most of any shifting. If you pin baste first, you will not be able to glue baste. If you glue baste first, you will have no need to pin baste. I am a glue-er!!

Batting, or not. Personal preference. If it is heavy enough for your purposes, not needed. A "quilt" without batting is considered a "summer quilt" in some parts of the country. A throw would be one layer.

Quilting stitches, again personal preference, I usually go with width of hand/fist, maximum between stitching, regardless.
