Thanks Hunnib!
Yeah K, it definitely helps me playing with pencil and paper - BUT I do get through an awful lot of paper!
It does help with the "flow" action when you come to the machine - and I draw in the same direction as I quilt. For instance I descend down borders, so I draw down in columns when practising. I also find if I am FMQing something I am not too confident with, it is better to use a very fine thread, cos any wobbles wont show!
