Hey all, I am looking for suggestions on DIY desk chair mats. For years, we've never used chair mats and have ruined our linoleum floor. Now that we're moving to a house with a nice hardwood floor, I'd like to keep it nice. Desk chair mats are expensive!

Do you have any ideas for a cheaper alternative or a DIY project?

I did Google. They suggest wood mats, but I'm not too keen on that idea as I would rather plastic or some kind of transparent. Something not too difficult to make, either.

Thanks!
