Care to summarize what you learned from airbrushing? Lots of light layers?

I am planning a repaint, what would you seal the bare play field with if you could do it again?

I have a Silhouette Cameo, it cuts perfectly in terms of size but I have to scale images by 25% from Inkscape due to DPI difference. Wonder if there is something like that going on with your cutter. I also found there is a difference in how sizes are expressed in the Silhouette software versus Inkscape — whether dimensions include the thickness of an object’s stroke. I cut squares with different strokes to figure it out.
