The Artfire Cafemom Team is a guild of artists who all sell their artwork through a studio/store on Artfire.com. The common detonator is that all of their members are Moms, which makes this an eclectic group representing many different artistic mediums and many different geographical locations.
Their blog is also full of recipes and helpful hints for Mom's like time management and parenting tips. It's a great group, and I'm proud to be one of their members.
And, yes, one of my pieces is entered in the contest. To see which one go to: http://artfirecafemomteam.blogspot.com/2009/05/weekly-contest-flowers.html
