This is the card she came up with. I printed out a bowling pin from online clip art and used it as a pattern to hand cut the pins. We used a punch for the bowling ball and the little finger holes. I give her credit, she came up with the design, I helped her get the pieces cut and she stuck them altogether and addressed all the envelopes. Not bad for a 10 year old.
Here are the "goodie bags". Each pin is filled with little toy goodies and little candies.
And here is our cake.
