As a newbie to painting, I appreciate useful tips. Here are a couple that I can share:
First: when transfering an image onto a surface, try using chalk! Rub chalk on the back of the image (or on a sep. piece of paper and place under the image, chalk side down). Then trace the image on the front onto the surface. When the painting, drawing or whatever the medium is finished the chalk can be rubbed off.
Second: When blending or creating a gradation, side load your brush (flat or round). That way you are not trying to blend a harsh edge.
I hope these tips are helpful. Does anyone else have any useful tips they'd like to share? (The tips don't have to be for just painting!)
