I just found your blog but I'm having a lot of fun reading it. These cards are really neat and I like the envelopes that go with them.
And to answer Katherine's questions (which I couldn't comment on before because then I'd be entering my own giveaway!) the envelopes are made by tracing around a store bought envelope that I've unfolded. There are envelope templates you can buy that have holes to score the fold lines as well as the envelope shape if you wanted something more sturdy. The story of how I came up with Betula`Loo was my very first post.
Thanks for all your comments and happy Sunday!
