A bookmark, in a coordinating envelope, was posted out as the invite.
With it's practical usage, it served as a reminder till the event, and then of course, as a functional momento.
The two older daughters pink bikes, followed by a cream coloured baby carriage.
In reverse order, the 2 colours blend for the back ground panels.
With a thumbhole cutout, the insert slides out with the event information and an image of the baby carriage. The insert is enclosed behind the card.
