I'm still learning too, but I have found two things that have really helped me improve: A plexiglass extension table and a polish for it that allows the quilt or quilt sandwich to glide across it and the bed of the sewing machine. The polish is only 10.00. Here is a link if you're interested.

They also sell extension tables which was cheaper and thicker than the one Pfaff makes. I have no affilliation with the company, just a satisfied customer.
