It's usually difficult for me to make a CAS card, let alone one that is masculine focused, but, this stamp by Avery Elle is easy to work with. I've kept the card simple but colorful and am entering this into the current Send A Smile 4 Kids Challenge - CAS.
This SAS4K collects cards for kids and distributes them to hospitals throughout the US and Canada. The hospitals are very appreciative and have commented that cards for teens are hard to come by so I thought this image would work for a teen!
