I do a lot of quilting in the hoop. I have a Husqvarna Viking Topaz 20. It is a bit difficult to get the designs squared up in the block when hooping the quilt sandwich. I am thinking of buying a magnetic hoop so I don't have to close the hoop on the quilt. The large hoop is expensive though, $170 plus $ for extra magnets. Anyone have an experience with magnetic hoops? I use Aurifil 50 wt. cotton thread. I haven't had the best success with QAYG. The front of the quilt looks great, but I have trouble getting the back of the quilt seams to look good.
