A twist on traditional one piece backings. Very yellow...warning!
 

Hopefully this comes through!

Wow that is bright but i don't see a picture of the front of the quilt.......

Bright as a sunny day!

No front pic!!!!

I really like the back.

Ditto ... on no front picture!
Please do show us, so we can see how they coordinate.

I often do similar ... all depends on what I have leftover from the front to use. Sometimes it may be some extra blocks put together from the back. Though, I keep it simple enough that it doesn't compete with the front ... yet more than a plain backing in order to create some interest!

Your back is very nice. (I was going to say your backside is very nice but that sounds a bit personal) Yellow is such a happy colour.

I love it,I piece a lot of my backs,also add block or rows of flying geese etc.The back does not have to coordinate with the front completely.I just try to ad a little of the front.I am sure our GGG didn`t have huge pieces to make the back.
