Greenie- I would suggest asking your question (or searching) on Machine Quilters Resource. Its a website with all things maching quilting- for domestic, sit down or reg stand up long armers. I know I have seen this subject over there. I have looked at it myself and if I decided to really quilt as a business, it would be something i would invest in. I am not affliated with MQR..just a happy member.

PM if you need help over there. Its my other stop besides FB and here.
