I am quilting my experiment today with my walking foot. The front is stuck really well and I am not having any trouble sewing through the glue. The 505 on the back is not sticking as well because the batt is polyester. 505 sticks to polyester but because the polyester fibers shift, the fabric can shift as well. You can see the one spot above the umbrella where the backing has a little extra puffiness. I may go back and fix it later. I will post another picture when I finish the quilting. I am taking a break to post because I ran out of bobbin thread, of course.
