I got my will g's shea patchouli and #7 today. I put the patchouli soap in a tupperware bowl with about an inch of room on each side. I figured i'd need room for lather that is made on the side of the soap. it ended up sliding around a lot and i hd trouble getting the soap in my brush. would it be better to put it in a container where it barely has any room to move? how would that affect lather/water that ends up in the container?
