Hi, I'm brand new to shaving with a straight razor. I purchased a set at straight razor designs including the video. I have a question about the strop. In the video there is a linen part that you put some past on. The set that I purchased the strop is nylon. Do I treat it the same as the linen ones? The video didn't mention anything about this kind of strop. I also have another question. I feel stupid for asking this one. The shaving cream that came with the set, how do you get a lather from it?
