I prefer my backings to coordinate with my quilt also- I don't make that many and usually spend a lot of time on them, so I like them to match. This week I finished a civil war quilt I spent a year making and had ordered a wide back in the fall for it. It was red, so being a washer anyway, I did wash it and used color catchers. I measured it to make sure it would fit my quilt which was 101" square, and to my shock it had shrunk from 108" down to 96"! I was so upset I couldn't see straight! I have never heard of any shrinking that much- it was a well known brand name- not a cheapie. I ended up piecing it, but I can't bring myself to put it on yet. Has anyone else had this experience? I'm afraid to use them again when the width needs to be close. I am a new longarmer and wanted to prevent the seam going down the back to avoid puckers.
