To tie a quilt by machine baste the quilt as usual and mark where you want your ties. I was going to "tie" at the corners so I didn't mark. Set the sewing machine on zig-zag with the maximum width and an almost 0 length -
Zig-zag back and forth 15 to 20 times moving forward and back just a bit.
Then lift your presser foot and move to your next tie.
When you are done machine tying, clip your threads on the front and back.
Simple, fast and comfy. I have done this on other quilts and they hold up great. That is the secret for how I got the second quilt quilted so fast. :)
