The extra 10" equals four 2-1/2" strips for binding.

For me, 118" is better than 108". I am actually looking for a backing even wider than that right now. The quilt top measures 118" so I need a backing a good bit wider.

Many people have deep mattresses, and queen or king size beds. By the time a quilt is quilted it loses a few inches, so we have to start with a fairly large quilt top.

I like both. Since I make only bed quilts, sometimes the quilt itself is 108 which gives you no extra for the quilter to have any wiggle room to put the quilt int he frame. I have had to add quilt art to a couple of mine upon occasion. So I like the idea of the 118 inch width. Jan

I agree.

hello,
i want to share with you what i use for backing.
depending on the size of the quilt top, i use bed sheets.
alot less expensive and so much easier to use.

I agree; the 108" shrinks and then is definitely too small, necessitating buying extra. I had to add a 9" strip on each side of my backing cuz the 108" had shrunk 16"!!! so I had to use the extra I'd bought, just in case, since I'd never used such backing before. This was for a king size quilt.
So, YES, I would definitely prefer the 118" wide to begin with since I did not appreciate having to have a seam along each side after all, when the idea of the wide backing is to have it be one piece.
Thanks for asking; this is a sore subject with many who make larger quilts that a kingsize bedsheet won't accommodate.

I have a commission right now for a 110"x110" king sized quilt...and will have to piece the backing to get enough room to long arm it...so yes, I would think that size would be welcomed, especially by those of us who need the extra few inches for the long arming process. Thanks for the information!

I would also go for 120"

I REALLY love this width!!! We have a California King, the first quilt I made for it measured 106 x 106. So, 106 + 3 + 3 =112. That's 3 inches on each side that my LA quilter needs to have when she puts a quilt on her machine. It's great that I don't have to piece a backing then for my quilt.

118" is for King size
108 is full/queen
