Deer shed their antlers or lose them in territorial fights so it is quite common to find one lying around where there are herds of them.
This particular one had been at my parents' home for a decade and when I brought it home I felt that the natural tone just blended in and wasn't noticeable. It needed some punch. After a quick browsing of colour palettes, I settled on Payne's grey, magenta, and gold in acrylic. I found bottled colours easier to apply than spray paint.
I used masking tape to demarcate the colours but because of the ridges on the antler there were small gaps because of which some colour leaked through. Don't worry too much. After the paint dries, just touch up the lines with a fine brush. I used 3 to 4 coats of paint. Remember to wait overnight for the paint to dry before removing the tape and applying it to another painted area.
