Recently finished King size quilt top of old fashioned double knit (yes, double knit!) with flannel back and no batting. I tied it and stitched "knife edge" all around. By that I mean cut top and back even after tying, turn top and backing edges in to each other, pin well and stitch together. I used size 16 ball point needle, my machine never missed a stitch! On the spare bed downstairs, I have one made 1972 by my Grandma and the year is hand embroidered in corner. When kids stay, they remark about how old it is!
