I have done several (its a fun group to sew with and more of a social thing than a class) but our instructor is excellent and gives us a good colour board to start with and then points us in the right direction for fabrics that willwill lie together/opposite/contrast/tone and will also let us know the predominate print (can usually be worked out anyway from the amount required) so we are always happy with the end result. It is great fun to puzzle and gossip about how we think the final outcome will be! lol
