i would call the shop & ask if they are (assuming) you are already a paper piecer or if the class is geared to beginners-i am an avid paper piecer- love the technique and find it to be (easy)
that being said- the first time i tried it was in a class that was---way over my head- and very frustrating- i decided i would never paper piece again- and didn't for about 3 years- then came across something i really wanted to make & tried it again- with much better instuction--and much better outcome-then i was hooked---but that first experience was not a positive one- i would make sure the shop is gearing the class toward all skill levels before spending money on a class that may not go well.
or since the class is not til February- you could visit the Carol Doak website & do some learning on your own before class- she offers great tutorials-beginner patterns- lots of help- that would easily have you ready for any class that came along.
