When your bicycle-built-for-two becomes a bicycle-built-for-three, a baby is on the way! Let your message ride in style with these modern baby shower invitations. Fun graphic elements of a bicycle with baby carrier and flowing flag announcing your 'Baby Shower' make for a playful design in red and aqua. The front also holds the party details at the bottom, while the back side continues with the fun theme by featuring a design bursting with dots against an aqua background. These square baby shower invitations come with square envelopes which stand out nicely in the mail, but do require extra postage. You have the option at checkout to choose rectangular envelopes instead, which do not require extra postage.
