Most people prefer to send via PayPal kirkram@@gmail.com - remove the extra @. If you have another way that you prefer. I'm very flexible. I've had people send me self addressed stamped envelopes, etc.
I'm slowly adding other items as well. I like mostly paper crafts, got started in paper models awhile back. My primary sales are the paper plate makers.
BTW - I'll always combine shipping. I'm not looking to make money on this. I do it because I enjoy it and there are people who enjoy what I do. I just want to get enough to at least cover my out of pocket expense, shipping and PayPal fees if used.
