Patience is an understatement ......these are the tools I use for a lot of my paintings .......Brushes just started costing to much because I put a lot of pressure and sometimes use 4-5 brushes a painting so I use the tool alternative...cost once that is it...lol
It is not easy to work with these it took some time developing a technique ...Just finished this one today for Cancer awareness month.........Still a few minor touch ups left ...
