I've followed your directions for creating a paper mockup (it was pretty easy, thanks), and I have a question for you. In the version you made for your red pot, I see the pot edge snugs up against the stakes - which is probably good for efficiency when used with your gas burner. But when used with wood, do the small openings remainin at the tips of the triangle provide enough of an airflow exit for the fire to burn?
I'm making mine sized to work with an Evernew 1.3L titanium pot, and hope to alternate between wood and my GG Firefly alcohol stove (by using a platform insert similar to what you made for the gas burner head). A 6-inch stove top edge fits my pot much like what's shown in your photo.
Is the solution as simple as adding some ventilation holes near the top edge, or in your experience was this not a problem/concern? Thanks in advance for your help.
