I want to be able to machine quilt this one...any suggestions on backing?

what a wonderful pattern and great colors. no backing suggestions for you, though.

very pretty! Like those fabrics.

I would use the peach for the backing especially if you could find one with a peach on peach design

Very pretty!!
Since you are machine quilting it, you could use batik or quilting cotton as backing :D:D:D

Love those batiks.

Have to ask. What makes this a "Tatoo" wedding quilt (assuming of course you meant Tattoo as in skin ink).

I say peach too for backing.

Well, my nephew is getting married and his wife owns a Tattoo
shop (sorry sp. ?) And they both have lots of Tattoo's, so I wanted to do something with some color and not a traditional.
I think it would a nice size for a couch.

Try one of the "Stonehenge" fabrics (by Northcott). They come in lots of different colors and wide width (if you need it).

I like the green or the cranberry color you have in the front for a back!
