This card was inspired by a card made by this week's Featured Stamper, Sophie LaFontaine:
I changed the font and the colour combination. I used a Stampin' Up single Happy Birthday stamp from 2007 (don't have the name). Lining up the dots was another matter completely. In the end I stamped the navy dots first, using a row of dots from (probably) an old Papertrey set and then used the same stamp to stamp the green dots in between the navy. MUCH easier than stamping each one free hand!
