Most of mine are all one fabric but I have pieced them and loved the effect. It's all about what works best for the quilt.

I've recently gotten into pieced backing... just for the reason that it doubles the look of your quilt! Now you have a two-sided thing and can switch whenever you want. That's for bed-sized quilts though. I won't bother doing that with something that'll be hung. And yeah, it sure saves $ when you've already got coordinating colors from your stash.

I have been fussy about the back of my quilts but using scraps from the front would very much help with the ever growing scrap bag so thanks ladies . I entered three quilts in a show and didn't win but got a lot of tips of what to do on the next one. number one: don't enter LOL .

just finished a quilt with a patterned front and made the backing a scrappy with all the left over pieces from the front........worked out pretty good.......

I usually don't piece my backs but I make sure that they match but I have seen some beautiful quilts pieced with matching material.

Well, you are more daring than I. My husband calls me Doris Day, everything has to match. I am gradually getting past that with the help of other quilters, especially on the front pieced part. However, I have not graduated to not caring about the backing. It still has to match something in the quilt front as well as being one continuous piece for the back. Keep working with me, I still might get there.

I'm just finishing a quilt that I purposely made 'reversible' for our bed. If I get tired of one side, I can flip it to a totally different color scheme & style, yet it still complements the colors of our bedroom.
I used wool batting, making it an even more worthwhile investment to be reversible. And, will add a 'skirt below the quilt for the sides to reach near the floor.

I like to think my quilts re reversable, so I AM fussy about my backs. Often they are pieced with leftovers.. or something different that doesn't even "go" with the front.

Am off today to sew/gab and eat with a bunch of gals. We are putting together 250 !! autograph pillows for Camp Mak-a-Dream.

I often piece the back - just to get rid of fabric I'm unlikely to ever use.
Not in a pattern, just willynilly.
Usually bears no relationship to the top.

I always use material that I used in the quilt. I do however sometimes make the back in a geometric design or large sqs. rectangles and strips. I know a lot use sheets but no matter thread count they are a sheet and the quality of you fabrics in front. I do know a lot use muslin but again issue of quality. If you look at old quilts the backs fall apart even pieces in front that lower quality fab was used. I have a lot of my Grandma's quilts,and u can see where she used good and bad fab. Pieces have just fallen apart. So if u can afford it go for the gold.
