So far this year, I've only had to buy a backing or two but I buy enough so I know I'll have large scraps left over but I normally have to buy at least 3.5 x 108" backing anyway as the UFOs that are getting quilted this year are over 100" square so to be safe I buy that extra 1/2 yd. I have made 1 king quilt and 6 oversized lap quilts out of my yardage and mostly scraps so I'm finally seeing space on my shelves.
I also have another queen size quilt on the design wall partially finished but still out of my stash and some embroidery blocks I made 20+ years ago so I'm using up embroidery stuff also. And of course with this quilt, I have lots of large scraps leftover but I still have some throw pillows to make up to go with the quilt so I'm not quite done with those scraps.
I have 2 oversized lap quilts to make in 2026 but again will use what I have and I think I might already have backings for these so I won't need to order new ones.
