The LA here turns the quilt so the seam is horizontal on the frame. I can see a very large quilt may be too wide for some frames but most can be turned.

I prefer to make my backings with the seam going horizontally. It uses less fabric too. I make more charity and QOV than anything else.

49"+6"=55". I would cut the width of the fabric at 55", which allows 3" of backing extending beyond the width of your quilt top edges( if quilting on your domestic machine.) Allow extra backing if you are bringing to a long arm quilter (4" around the perimeter of your quilt top 49"+8"=57")

Cut 2 pieces at 55" x 44". Join the 2 pieces along the 44" side with a half inch seam allowance to equal :55" w x 87"l . Trim the 87" to 62". You have a backing size of 62" l x 55" w for your quilt top of 56"l x 49"w.

...so I did, and Citruscountyquilter's instructions worked brilliantly. It's not perfect, but for a first attempt is pretty good. [ATTACH=CONFIG]571861[/ATTACH]

I saved John Flynn's calculator and found a video. I'm more of a visual person but still want the calculator. Then I'll think about it.

Gorgeous quilt Boston! If you are hand quilting, the less seams- the better. Long arm doesn't matter so much. I hand quilt so those thick seams are harder to quilt through. (threw???)

I like the diagonal back. It is fast and easy and you use a lot less fabric.http://www.multi-patch.com/
