We made some fish we can "catch" with a magnet. Kids have just as much fun with plainlooking fish. But here is how we gave them some style:

I had her choose two colors of rectangles, and give each one a pattern with the same color of marker ("squiggles, stripes, dots, circles," etc)

Mine are on the left, hers are on the right. We drew a fish on one of these,

then cut them out, one on top of the other to duplicate.

We cut triangles out of one of them, which will be glued on top of the other...

Then put a paperclip on each fish, for a magnet-on-a-string to pick them up.

This design was my inspiration. I did this as my first experiment with my digital textures style.
