dumb idea?

[DeesBalls]

Okay, so i have a ball python and BRB that i have an idea for to get humidity up.

i am going to take a piece of fabric ( from walmart ) and put on top of 3/4 of the screen lid

thought?

i was thinking of putting some holes into the fabric as well for ventilation.

i am only doing this until i can afford some really nice vision cages, or something of that nature.

also what would you use to secure the fabric to the lid?

thanks for help!!
