Pet portraits are a common request and I love to do them.
Since you can not buy pre-made velvet canvases, I stretch my velvet over stretcher bars. Your painting starts with me putting the stretcher bars together, cutting the velvet to size, folding it over the stretcher bars and carefully stapling it down. This is based on the traditional method of canvas stretching.
I then make a drawing of your requested image and transfer that drawing onto the velvet.
