I have learned, after MANY messy tables from crafting, how to keep the table clean. As soon as I thought of this it was seriously a DUH! moment.
Instead of having to wash the table and try to get paint off of the wood and such.. I just lay down a table cloth. I bought a picnic table table cloth on clearance for $.99 a couple of years ago at Target in hopes of using it on a camping trip (which we never went on) I was going through stuff a couple of weeks ago and came across it. I pulled it out and seriously said, "I know what I can do with this!" and nobody else was here.
It works great. I don't even bother wiping the paint and glue off of the cloth. I just empty it off, fold it up and put it in the craft bin.
That's what works for me! For more tips go check out Rocks in my Dryer.
