I have a Grace Mini Pinn frame, considered a mid arm, & have it set up in crib size & I love it! I don't do alot of big bed quilts, but figure, if I want to, I can do it in sections, then just sew the sections together. This is another option to think about on your machine you have now. Something else, you can quilt as you go on your blocks, that might work too. My Grace frame was $500 at the time I got it, just a couple of years ago, I think. Do some checking, lots of less expensive options out there if you decide you want a frame, & lots of ways to quilt on the machine you have too! You might want to look for a spring loaded foot too, & try free motion quilting, even for straight lines. I found a generic type spring loaded foot for my machines, cost $10, versus the one Viking sells for my Sapphire, which costs $40!.. So keep asking questions & trying different ways to quilt, don't give up, & you will figure out what works for you!.. Good luck, & nice quilt too!
