I read the quilt ---- I hang it in my sewing/computer room and stare at it, then I decide what I'm going to do. I then put it on the machine and TOTALLY do the opposite -- well not exactly opposite -- but at least 50% of my plan changes!!!! LOL
I also do a lot of research online and in books. I have looked at quilting techniques and ideas so much that some of them are imbeded in my head.
Check out www.mqresource.com. MQresource is a forum where some of the professional longarmers hang out. They have tons of ideas and help!!
Welcome and good luck!
