I want to make Dinosaur cookies anyone have any ideas on how to decorate one? Thank you my son will love you guys for your help.

I'm guessing you don't have a cutter? If you don't, you can google dinosaur coloring pages in their images, and come out with a lot of cool pictures. Then I would take one of those, and scale it down to the size cookie you want, print it out, trace it onto cardstock or card board and cut out again. That'll give you your template to cut cookies. From there, I would get your son's input and see what color he wants them, etc or even get his help to decorate. Depending on amount of detail, just look at the picture you printed, and that should help you out. I made these this past weekend, and my bf's little boy loved them...( I used a cookie cutter)
