I use my HV Topaz 20 with the embroidery attachment to quilt most of my quilts. After the quilt is sandwiched, I hoop the each block and run the quilting design. There are previous threads on this site with a lot of discussion around this topic. Perhaps a search would help you find the discussions. I sometimes supplement with SID or use my walking foot, or FMQ. But doing the entire quilt using the embroidery attachment is possible. I have quilted many queen size quilts using this method. Good luck!
