Unusual Card Shape--Last week as Guest Designer for Stampotique

Hi artsy pals,
   This is my most recent addition to the Stampotique Designers Challenge... the theme is "Unusual Card Shape".... It does fold flat to mail, but would take extra postage for sure.
  I will certainly miss being the guest designer, but I'll still happily play along each week!
 
                          What do you think?

Thanks for stopping by!
