I love doing it all myself, I really enjoy the process: thinking up the project, shopping for fabric, piecing, sandwiching (this is only ok, it's not super fun but I don't hate it either), quilting it, going shopping for binding fabric..I learned a long time ago that when I buy the binding fabric ahead of time I end up hating it with the finished sandwich lol. I've rented a longarm twice for king size quilts but it honestly wasn't that fun, it was loud and the store was busy and people kept coming over to have a peek and wanting to talk to me lol. I did enjoy the difference of moving the machine rather than the fabric though.
I have a Juki 2010 now that I do 95% of my sewing and quilting on but I've done countless blankets and quilts and other fun things on my DSMs. The Juki has so much space comparatively, it's crazy!
