I've used a big piece of leather on my desk for more than a year now.
I love it. It's soft and looks great.
It works great for the mouse pad too!
make himself a mouse pad as well!
We took a scrap of leather...
and marked out the biggest rectangle possible on it.
It's slightly bigger than standard size, so he loves the freedom!
But not quite as big as mine...dust and all! :)
