That's great. Congrats on finishing the first one. You've got a health attitude about learning.
My investment was $2500. I bet I could get more than a handful of quilts quilted for that amount.
What pushed me into the purchase was having just about ruining my shoulders and neck passing a King quilt through my Janome 6600P. I love that machine, but quilting a king sized quilt with a moderate batting was brutal. I'm 44 years old, in good shape, active, etc. I am still suffering from a sore neck, shoulders, and numb hands from that project.
