Sometimes I just doodle for the fun of it. I always have new ideas for card designs, most of which get printed, but some I decide to keep and develop at a later date. I have to ask myself if the design is commercial, will it work as a greeting card. It doesn't hurt to be a bit ruthless with your own work at times. That is not to say that they won't appear as prints in the future because I always try to create work that can be framed and appreciated as art, especially as some of my designs are a bit unusual.
