Four of my grandchildren have birthdays in September, so I usually start working on cards
at the end of August!
For my youngest grandson, I made a "slider" card using some Disney paper and characters.
For my third grandson (of five!), I found some paper with alligators on it and used one of SU's stamps to add the greeting. I stamped the date of his birthday on the card; when he pulls up the insert, there is a big "Happy Birthday" greeting and space for writing a note.
