Great quilt. The problem with the loops on the underside may be the bobbin is not wound tight enough. My mom and I messed with her long arm for a few months and it turned out to be the bobbin winder on the machine just didn't do it good enough. She bought a stand alone bobbin winder and totally solved the problem. I bought on from Joanns and it worked but it didn't wind it full so we were always running out. So she got one made for the job.
