I first started quilting on my DSM. Then I got the handiquilter frame and used my Juki TL98E. I got rid of it and went back to just quilting on the Juki without a frame. I make large bed size quilts. Once you add the frame and half of a queen size quilt into the Juki throat your quilting space becomes very limited. So yes, I downsized back to a DSM.
I just recently learned about a quilt shop here who rents time on their long arm machines. You have to take a certification class first and then you can rent time. I have now quilted 2 quilts on their machines. Both of them were designs I could have done on my DSM (stippling and vines with leaves). However, I did not have to sandwich the quilt -which saves me a lot of time - since I still pin baste. One of these quilts had been a top for over 10 years and the other for over 6. So YEAH!!!! Now they are quilts.
