I also found some fun invitations/notecards from BizzyBee Creations that were pink, green and brown. She's also got some other cute cards on her site. Check it out.
Brown isn't one of the colours that I usually wear, but I am sort of coming around to it recently. It all started with a gorgeous brown linen skirt from Talbots that I normally wouldn't have looked at twice. Then I had to figure out what to wear with it and started noticing how good brown looks with some other colours like pink, green and blue, especially the paler shades of these.
