Thanks a lot, you're so sweet !
I used a very small paintbrush (3/0), for the paint : a black, white and blue acrylic ones (I've used a glossy one for one eye, it's better for the noise).
When I wasn't satisfied, I used a Q-tip with a little drop of argan oil so as to erase the mistake, it's very efficient. I tried many times before being satisfied.
And to finish, I used a toothpick for the 2 white points in the eye !
You know everything now and I hope it helps you !
I'm very impatient to see your renovations TequilaMockingbird...
