Has anyone tips for using shading technique using acrylic paints?

I like to use extensive shading to create three dimensional affects when painting. Using acrylics is new to me! Do I start with the lighter colour and work the various shading colours in layers over the top? Will that work, or is the whole thing going to smudge? Also, when the work is completed, can I varnish the canvas, to give it a glossy and cleanable finish?Has anyone tips for using shading technique using acrylic paints?
i've never varnished a canvas.


but like the other dude said, go from dark to light. if you don't want it to smudge, don't use a TON of water. and it's best not to use paints straight from the tube. try blending them a little on your palette before applying to the canvas.


--remember to make the edges and corners of your painting darkest, this will draw in people's eyes to your main focus point.


--if your brush has a ton of paint in it, wash it out. having it clogged with paint isn't good no matter what you're doing.Has anyone tips for using shading technique using acrylic paints?
It's usually better to go from dark to light. You can even clear coat with different media between coats for a deeper effect. I've never tried using varnish on canvas, I usually use a spray clear coat.
