Seed Catalogs, 2 a day arriving, uses....... Junk mail??

I have excluded myself from as many junk mail list as I could. Its not just green but self sufficient as well. So with the other stuff I get in the mail I place them on a pile that I will use later on in the garden this year to keep the weeds down. I also make my own homemade paper pots Year after year you will enjoy using these easy to make and use pots.

Junk mail ideas are wanted???
