I use Batt Scooters for all of my machine quilting - I find them helpful for straight stitching with the walking foot and for free motion quilting. They give me the traction that I need to ease those big quilts that my bare hands just can’t manage through the machine.
There are two sizes included in the kit. The smaller one, Baby Batt, goes under your right hand where the quilt is scrunched up and you have less room. Place the Batts on your quilt with the pointy sides facing each other, then cover them with your fingers, but leave your thumbs on the quilt fabric. You will be amazed at how easily you can move your quilt with these!
They are the first things I pick up in the morning and the last things I put down at the end of the day.
