Here is a little gem on how to get the clay out of Highwater Clay boxes. I think Doc Welty told me this little secret. (Shows how stupid I am since I never figured it out myself!)
Since they don't tie them and they just drop them in, instead of opening them from the top where it is hard to find anything to grab on to, just turn the box upside down and open. Then the bag is right there.
It might make your life better?! Or not!
