substrate question

whoever uses paper towels for substrate in a rack, well how many sheets do you layer in?

I use Reptibark for my BP, but in my hatchling corn setups I use one layer of paper towels...

I put one layer in.

Because I have to change it so frequently, it works better that way.

To make sure that the towels don't get bunched up in the corner, however, I weigh them down with the water dish or hide.

It works well that way for me.
