I've been playing with Microsoft Paint(MS Paint). If you have Microsoft software you can use Paint also. Here are some of the things I've been able to do.
On the above I put the tatoo pattern from MS Paint into a frame design from MS Word and saving them and re-inserting them lined up these doors. I've love to have this as a room divider somewhere in my home.
This was the first face I did. It could be used on a T-shirt, if you don't mind being too scary.
The above is just plain pretty to me. And then you can reverse the colors in MS Paint, shown below.
