I'm wrestling with Minkie right now! I'm using a vertical design Minkie for the backing of a quilt...no batting. Was advised the Minkie would be enough to make the quilt warm. It's lovely. I stitched in the ditch (remember now, I'm a new quilter) and I used a walking foot but still the Minkie had a mind of it's own because of the groove. I took it to the shop yesterday and the quilt person told me Minkie stretches, use a lot of pins to hold it to the quilt top, and try using a longer stitch so the machine foot can get over the fabric bumps more easily. I'll try that today. I was ready to pick it all out and hand quilt, but I try using a longer stitch.
