Zentangle rainbow ATCs #5 - Blue

I'm going to run a series of nine zentangle ATC swaps, each one a different color, so that in the end they will fill one whole protector page. We'll be doing red, orange, yellow, green, blue, purple, pink, brown/sepia, and grey. Since it's senders choice feel free to get a head start on the upcoming colors :)

This one will be for a standard size ATC that features a blue zentangle, though you may still incoroporate black and white, and may use as many shades of blue as you like. ATCs should be 2 1/2" by 3 1/2" and on a sturdy backing so that they will make it through the mail system safely.

Happy Tangling
