The 17th Challenge at the Friday Flashback Blog is to re-post your first banner.
I've never made an actual wall-banner, but I have made a few banner cards. Here's my first one from January 2009.
This was for a Moxie Fab World Banner Challenge ... the letter flags reminded me of Tibetan prayer flags. This rahter large card was displayed in my studio for a long time as a source of inspiration.
