After CookieCon 2017, I was anxious to get home and try The Painted Box (Angela Nino)'s awesome watercolor techniques. But while I was waiting for the supplies to come in to make my watercolors, I remembered that I had an Aquash water brush that I could try out to at least get a feel for the watercolor effect.
This brush is not expensive and it's easy to use. Basically it allows you to fill up the "pen" with water and then load color to the brush and paint on the cookie. (I used it on glaze icing with success.....but I'm not sure you can use it on royal icing the same way.)
Once you're done with a color that is loaded on the brush, you squish the body of the pen to push water up into the brush and "clean out" the brush. (You don't want to actually squish the brush while you're painting on a cookie or you'll have a messy puddle.) Once there is only water coming off the brush, you can move to another color. Pretty cool!
For these cookies I used airbrush colors since they are already very liquid and not too concentrated. I chose AmeriMist Electric Airbrush colors this time around. It definitely made for a SPRING effect. :)
