Just added circus-themed invitation designs to the shop! I can also take care of making prints for you.
I'll be adding labels, tags, thank you cards, and a banner design to coincide with the above invites very soon. Remember to add yourself to my Facebook page to keep up-to-date with new designs and discount specials.
Oh yeah, there are a couple of free circus templates you can use (banner and tags). Be sure to check it out.
