Hi, I am building a solar dehydrator from an old wardrobe someone gifted me. It has some holes where the screws were now that I will no longer be using them. I need to fill them up with something to get a good airflow. I was thinking maybe some homemade glue from flour mixed with sawdust or something similar? Any ideas?

If I wanted to fill a screw hole I would just use a piece of a cotton ball.
I save the stuff that comes with dear hubbies vitamins so there is no cost involved.
Just something I learned from my grandparents.
Though I think the flour, water, and sawdust paste would work too.

A wooden toothpick or piece of wood whittled to the right size, and some water resistant wood glue (like Titebond 2), or if you want to be all natural, some pine pitch. That would soften and drip if thick when it gets hot; maybe mixing it with a stabilizing powder like flour or clay dust... or use just enough pine pitch to gum the tight-fitting toothpick into the hole. Cut/saw off the projecting bits of toothpick when the glue stiffens up.
