I have to say, I am enjoying my first vintage soap. I could see a Yardley in my future.
One question... my lather at times seems air-ey. I'm using a scuttle and the problem doesn't go away with more agitation. Does anyone recommend more/less water? Loading more/less?
Could be your water ratio, but I'm betting you're not loading enough. Try loading more. A LOT more. Don't skimp! I know it's a vintage soap but it's still gonna last for ages. So LOAD that brush! I'm betting this will solve all your problems.
