An airbrush is expensive initially, and I want to try some accenting, smaller areas, or marking with a template before I spend too much. I have seen videos online for making a simple airbrush out of parts from household objects (such as a pen) with canned air, or blowing canned air over the tip of a marker to create an airbrush effect. Wondering if this would work with an edible marker? How does the appearance of this technique compare with a real airbrush? Have any of you tried something similar?
