I LOVE this quilt!!

Yes, My thoughts exactly. I would love to see an orange back w/ white thread. Juicy!

Are you going to quilt it yourself? As for me, I like to use at least a mottled color as someone else suggested because I don't want my FMQ on my Pfaff to show up so much. At the least I would do a practice piece using the backing and batting that you plan to use, along with a leftover block. I always end up making several of these as I audition the quilting design I want to use and the batting. Your quilt is beautiful. I understand your wish to use DH ideas.

With all that white in your beautiful quilt, make sure you use a white cotton batting. I have had good luck with Warm and White. I too would suggest a mottled orange back for a little interest. Can't wait to see it when it is finished.

I'm not sure how this would look without auditioning it. Perhaps an orange binding with your choice for backing?

Love your quilt top!

Very nice quilt - you did a great job!!

I personally use medium to dark colors for backing most of the time. I've not had a problem so far with them, but I haven't used white or even really light pastels on the tops either.

Since you are concerned about the color, I would go with one of the lighter orange fabrics rather that the darkest or brightest orange.

You might also consider using a white polar fleece as your batting to eliminate see through. Although I think any white "felted" batting would work well for you. I would not recommend using a poly fiber batting as that would probably not be dense enough to prevent shadowing.

You've done a beautiful job on this!

Your quilt is fabulous! I have done quilts with a lot of white on the front and use either Warm & Natural or Warm & White and never have had a problem with the backing showing through. Although, I tend to use more lighter colors on the back. I think the idea with a mottled orange would look great!

Love your quilt top. The colors are so happy. I will leave the advice to the experts as I as still a newbie.
