A (Definite) Handy Alternative
From quite a few Web-sites, i have come across artists recommending paper-towels (even towels themselves)....for removing Paint from your Drawing, Brushes, etc.
Unpredictable, in the execution. And of the consequence thereof?
What if you're out-doors?
There's something everyone does have at home.....that certainly does eliminate those 3 'question-marks'.
Works very well......as a 'sponge', to lift off excess paint, to clean your brushes and palette in very quick time.
Most important of all, if you really have to 'answer the 'Call of Nature' (use the toilet, for real!)....outdoors, well, you don't have to cry for Help, and let everyone know you have no toilet-paper, now is there?
You're already..carrying your own supply!
(Just sure it is a 'full roll'.....while you are outdoors. To be on the safe-side.)
