I meant to post to you when I saw your post about Dorset buttons, I went on a two day course about 25 years ago, think the tutor was the curator of the button museum, anyway it was a brilliant course we were shown how to make all the different styles. I found it was so useful to make my own buttons, and some I have turned into earrings. Since then I have run a couple of workshops for spinning guilds. I was so pleased to find I had Dorset ancestors but yet to find any button makers but keep looking the nearest I have got is a hat, and umbrella maker.
