Blue Cookies!

My mother's birthday is on Sunday so I decided to make her some cookies. She loves blue so I started with a blue base, now I just need to figure out what to do on top! I am thinking about trying my hand at the pretty lace designs I have seen. Unfortunately they are a bit crispier than I like because the propane tank ran out right after I finished baking them so I don't think the oven was keeping a consistent temperature, OR maybe I just left them in too long! I need to start setting a timer... Anyway I here is the before shot, I love this Wilton royal blue color.
