2 to go

so far I have 8 masks and I am half way through drawing the 9th. I am going to make 10 masks in total.
After I have drawn my last mask I will start designing the books.
The books will be A3 and each page will be double sided. There will be the same mask twice in the book, one which will be perforated and be able to be taken out and worn and the other to stay in the book with information about the character and how the peson wearing the mask should act, I will also give them little tast to complete to do with the images on the masks.
I need to talk to someone about how I will bind the book. Maybe a Japanese bind.
