Hey Copic chicks… do you have one of these?
    

And perhaps some of these?  You know that you can move beyond the flat surfaces and attack other things, right?  How about some blow / spin-art style cookie decorating?

Drop some food coloring on top and go all 'spin art' on your holiday cookies!

Can I advise drop cloths / aprons strongly enough? Nope.  But SO MUCH FUN!

Even Martha has gotten into the act.

This is serious fun.

No using Copic Markers on those cookies though, ok?  NOT edible.

Make something.
