How to make a yoga mat sticky again?

I own a few yoga mats and have found that my most favorite one has lost almost all of its stickiness.

So I went online to see if there was anyway to re-sticky my mat. The skidless towel may work for some - but without a lot of water, it did not really work for me.

Metafilter had lots of advice.

So did All Spirit Fitness.

Fit Sugar has recommendations as well.

I think it might be time to wash my mats again.
