I've made several of these, but forget to take a picture of them before I send them out. They are easy to make and do fold flat for mailing, They require a little extra postage because of the size but I don't mind.
This is a monochromatic card I made in shades of cream. I thought it might make a nice wedding, sympathy or get well card later by adding the appropriate verse. I never seem to have enough cards on hand for these occasions.
