Once upon a time, a long long long while ago, someone very generously shared this over at the docrafts forum. I am really sorry, as I can not remember who it was. If it was you, please leave me a message, I will credit you accordingly and link to your blog.
Just been to a demonstration, and one of the topics was bow making. I referred the ladies to my blog, and told them it has been a while since I have posted it (July in fact). So for the ladies from my demonstration, I have reposted how to make this bow using the fork. It has been photographed step by step. Hope it helps.
I will post the card I made using this bow tutorial later this week.
