I prefer to use wholecloth backs. Using blocks in the backing is sometimes hard to match so they look straight. By the time I get to the backs I am tired of piecing. I guess I am getting a bit lazy too.

I have used all three- wide backing, 45" backing sewed together, and pieced . The wide baxcking is by far the easiest, then the 45" sewed together and then (never to do again) pieced. I just finished a 80x90 quilt that I pieced the baching by sewing 6" wide strips together. I had extra fabric and I wanted to save $$$. What a chore. It seemed like a never ending process and not worth the $$ savings. Also it was hard to center the quilt top on the pieced backing. Also I am not really picky about my backing as long as they coordinate with the top. In fact I do not like the backing that I pieced for the last top. As for the 45" fabric- I like Kona cotton- it comes in many colors and has a nice hand and seems to add body to the quilt

That's so cool. Love it.

I usually use 45" fabric sewn together. More often than not I use flannel for my backs. Sometimes I piece some fabric from the front & incorporate it in the back, sometimes not. I have done one all pieced back. It took quite a bit of time but I was determined not to buy fabric for that quilt. I liked how it turned out & I would do it again. I find the center of the quilt back & pin all the way across the width of the quilt then, by feel, line up the center of the front with the back using the feel of the pins as a guide. Not a real fancy method, but I've had good luck keeping my pieced backs lined up straight.

I prefer the wide backs. I haven't noticed a difference in quality. They are a little cheaper to buy for the square footage that you need. I have used some left over wide backs for piecing and for borders.

I've also pieced the backs, usually a full WOF in the center, and half a WOF on each side. But you end up with less than 90" that way,and my quilts are generally wider than that.

I wouldn't add to the thickest of a T-shirt quilt. I would use whole cloth.

I LOVE, LOVE, LOVE a pieced back. It doesn't have to be intricate - I use fat quarter chunks, but it is so much more fun to turn over a quilt and see something else going on, other than a plain fabric, or heaven forbid, muslin. (Sorry, muslin fans, just my opinion)

Nothing better for me than a good quality muslin for backs....when washed, soft as marshmallow, and what a way to get a whole cloth...although I never turn mine to backside...why did I do all that work on the front! Save all that good printed cloth for the front of the quilt.......that's what an occasional scrappy is for. JMHO

What a wonderful idea...

I use muslin for backing AND as blenders on the front. Just sayin.
