Here's something fun I just completed - a set of matching (sorta) ACEOs.
Here's how I made them.
I began by painting an abstract painting. I've just purchased a book about painting abstracts. You can read about it here. Painting Abstracts
Then I painted some long curved piano keyboards. My wife thought it looked really cool, but I had other plans for it.
I then mounted playing cards (which I do for all of my ACEOs) on the back of the painting not being too concerned about where exactly they ended up.
After that, I cut them all out.
I think they ended up looking really great! I think they would make a perfect gift for a musician in your life.
