I did a queen size, ( quilt in my Avatar picture) but only stitch in the ditch on my Brother Innovis QC 1000, and it was a real test, I took about 3 days to do it, as I have trouble sitting for long periods due to a back condition.I will have to do the next one on the Grace Quilting frame, just lack the confidence to do FMQ on a large quilt, but I have done a couple of throws on it.
