I am *terrible* at drawing, which may surprise you when you see this picture...
I had help drawing it though! I used this website as an inspiration and drew the bamboo with sharpie. Next I placed another sheet of paper over my bamboo and began drawing random leaves. I messed up a lot but I finally got some I liked! Next, I scanned the bamboo and the leaves into my computer and then, using Photoshop, I cut out the leaves and placed them on my bamboo. Finally, I placed my crane in the image. I rather like how this turned out even if it was "cheating."
This is another one I made! I'm actually rather good at the random abstract backgrounds, not so much with things that have defined shapes. I did add the strip, circle, and crane in the middle with Photoshop. Also, there are some curvy lines at the top and bottom left hand corners - those were not there in my original drawing, but in Photoshop I figured the corners looked empty!
This is not a coloring page, but an example of a card. It's something older kids might have fun doing. The art-form is known as "zentangle" and is sort of abstract shapes and stuff. A lot of zentangles are really intricate (and take a lot of time) but mine is really simple and sort of fun. Also, I like how the crane looks as if it is flying!
