Artist Trading Cards and Such
The "rules" for artist trading cards are simple. The piece must be 3.5 x 2.5 and mailable; and ATC's must be traded and never sold.
Our groups usually run for six months with each month having a theme. For me, the creative discipline of having to produce a deliverable on a deadline is a healthy challenge. On the receiving side, seeing a simple theme interpreted in so many different ways is inspiring. This month's theme is: botanical.
My entry was done with walnut inks (yes, I am allergic...just careful not to touch), fine glitter and alcohol ink in a spray bottle and wax pencils. Because ATC's are small and because you have to produce them every month, it allows for a lot of "play" and experimentation--which in the end winds up making you a better artist.
