Carla Barrett, over at Step on Pins is starting her next Quilt Whisperer course on January 9th. I took the course last summer. It is very professionally done, with videos, narrated powerpoints, and the ability to ask her questions on her forum. The class materials stay available for 6 months afterwards.
The course covers how to decide on quilting designs for your quilt. This is the hardest part of quilting to me, and she gives LOTS of ideas. She even takes some students quilts and shows how she would quilt them - and why.
I highly recommend the course. It is well worth the cost, in my opinion!
