I've been working with the acrylics now for about a week and a half, and doing as much practice and research as I can. The above are several winter paintings I've finished with the Interactives this week. Blending is the hardest thing to adjust to with the acrylics, and I've found some really good information on techniques on Wet Canvas. Now www.wetcanvas.com is huge, enormous. And I've gone there a couple of times without any luck (high levels of confusion and frustation), but somehow I stumbled on a good resource this time around. It's the Information Kiosk under Acrylics, and inside the Kiosk is a nice list of "classrooms" that you can visit and read. All different topics. Here's the link to the Kiosk: http://www.wetcanvas.com/forums/forumdisplay.php?f=329 I think it'll work. From there you can pick a class to visit. The one on blending techniques helped me enormously. Also the one on glazing.
Today I mixed "slow" which is a medium for slowing down the drying time of the paints, and also some Gel Pumice (it was a Golden sample I had gotten at an art store and saved), and the combination gave me extended time and some extra heft and tooth to the paint. I used my water sprayer some but not as much, mostly to spray the palette, not the painting. And I scrubbed when I wanted blending with a damp, clean, bristle brush and found the blending easier to manage.
For the small branches and trees I used some "Liquifier," another Chroma product for their Interactive line, and that not only thinned the paint, but it (somehow) kept it from turning transparent (as you'd expect.) I was able to get thin, solid lines with a rigger brush to add branches to the trees (bottom two paintings.)
And there's my update for the Interactives. I'm starting to get the hang of it. You really do have to stay with it, and get past the frustration at the beginning. Working WITH the paint is the trickiest part, but the mediums really help you out.
