I am considering using a touch of acrylic to add focus, for example in my last watercolour the boat was originally blue, navy or napolean, whatever you want to call, a rich dark blue, but you could only see the last few brush strokes as the weather and time have taken their toll.
I have been thinking few dashes of acrylic blended in would show that I was thinking of how that boat must have been, and thats what I think most people think when they pass the boat.
I can not change that painting now and I don't want to, but I thinking for further reference what do I need to know about mixing the two mediums, I am not talking about whole swathes of a painting, just the odd highlight, or too draw attention to a certain aspect or point of the painting.
Is there any pitfalls? Do they play well together on the paper?
And can I still post them in the watercolour encourager forum, as long as I say there was a little acrylic dash here and there?
