Since I discovered this craft last spring, I started the web store with minimal inventory, and I think the beginner kits are the very best thing going. I've just ordered more, because I really would like to see more US parchers (which is what we are called in the UK.) Most of the templates are sized a bit differently than we American cardmakers use, but you can easily make your own envelopes to fit.
Or, as I have done, adapt the size to A2.
I carry only PCA materials, and can order anything to add to someone's order or to my inventory if it becomes a popular item. I'm not looking to stock a warehouse, just enough to get us all supplied with the necessities.
Please tell all the papercrafters and cardmakers you know in the US to join me in learning this new craft. It is really gorgeous. Visit what I have at ParchmentCraftUSA.com and let me know what you think.
