I have a variety of items for sale on a great website called Bonanzle. It is free to list your items and the fees are very reasonable for selling them. It is a friendly community of sellers and buyers who engage in chat and forum posts. Chatting and posting is not necessary, but it is fun and informative.
I have several vintage matchbooks that I haven't found any place else. You can find books in my booth on various subjects, including sewing, crafts and home school educational books. There are some one-of-a-kind collectibles for you too. I have sewing patterns from various decades as well as some homemade items.
You never know what I may find to place in my booth, but it's Always A Variety!
