I have just refined my way of making them as well, so they are easier and neater! If you would like me to share I can do a quick tutorial, they really are super easy. Just 2 pieces of fabric, and I add some wadding/batting in between, not essential. I do also add a tab, which is probably the most fiddliest bit, still looking for an idea on how to improve this part.
I am always searching around for interesting buttons with a shank.
Visit my little craft community would be lovely to share ideas and projects and have a crafty natter.
