Everyone will be as happy as a whale at sea when they see these whale baby shower invitations. The colorful stripes forming the waves, bordering the edge and filling the back put them over the top on the adorable scale. And nothing beats a smiling whale and a trendy color combination of aqua, orange and green. The circle shape will make a stylish impression, too! Square envelopes are included with these baby shower invitations, but they do require extra postage to mail. You have the option at checkout to choose rectangular envelopes instead, which do not require extra postage.
