Rockin' Rug

So the description on Pinterest says:  "Glue Gun, Scissors, River Rocks at the $1 Store! and Shelf Liner (or mat) in a matching color."

I call bullshit.  I bought a rubber mat and the glue gun does not stick to it, or the rocks.  It takes Tacky Glue. 

I wouldn't suggest a rubber mat.  Or one purchased at the Dollar Store.  You'll probably want one bigger to avoid your awesome new welcome mat looking like this:

 A little underwhelming.

But at this door?  Perfect!
