I used a stamp set from TAC that's been discontinued - but everyone has a set similar to this one I'm sure.
The base card is Pixie Pink and the DP is some I found in my scrap drawer already cut - I'm not sure who it's from. I stamped the little candle from a SU! set called Birthday Banter for each day of the month except for the actual birthday. I stamped the date for the day. I then punched out the circle using my 3/4" and 1/2" circle punches.
The cupcakes are from a Stampendous set "Hey there Cupcake" set and the present is also from them. The hat is from Hero Arts. I stamped each and cut them out and positioned them at different places on the card. I used some stickles to jazz it up a bit and I was done.
