I used Prismacolor pencils and personalized the card by adding glasses and curly hair. It's a stunning likeness, as you can see from the photo below (which I took today for his grad invites).
Happy Birthday to our new adult son...who cannot cuss indiscriminately around us even though he thinks that's what 18-year-olds do. Thanks for being my baby and for being so funny and cool and kind and talented and cute and helpful and I'll stop now but I could go on and on. Love this young man.
