Do NOT dry in the sun, dry inside or outside in full shade or better yet in a dark place. This will preserve the color of the pepper.
Air circulation is good to have, a small fan works wonders and speeds up drying time dramatically.
If your house is air conditioned like mine it is a dehydrator too.
The humidity is much lower and you could put vents in a closet with a small fan.
Some of the larger computer fans work great they use very little electricity and are quiet.
And they already have mounting holes.
You would then put another vent in it for air to come in or out.
Since moisture laden air is heavier the outtake should be on the bottom and the intake on the top.
The upper intake vent can have a small hepa filter that would filter out much of the mold spores that would be undesirable in the closet.
After they are crispy dry, put them in a mason jar and store in dark cool place.
Or put in a blinder and chop up for flakes.
I buy peppers already dried here and make my own flakes, they are much brighter and redder than the store bought flakes.
But like others have said nothing adds that
South West Flair to the house like a string of peppers for all to see.
