This is a chinese book translated from japanese which is titled basics/foundations of pockets. I am not sure if there is a english version.
There are great details of the various type of pockets mainly set on and set in.
I am more interested in the side pockets for skirts.
I think the diagrams are very clear. The author has other books too on sewing. for example sewing machine basics as well as paper pattern sewing. Hope i can find them from the local library soon!
