Thanks for the info.
Hopefully soon I will try it out.
Also, I see that you used metal corner beading. I have seen plastic also.
Any advantages to using one over the other?
I would think plastic would be easier?
I have seen those paper faced metal beading, and I would think that you would have to have very level and straight corners? I don't think all of mine are really that straight and level and professional looking, so I imagine I would have a harder time with the paper faced metal strips.
Do they have smaller attachements to put on the drill to mix the mud, because I cannot mix a very large quantity, as I only have short little periods of time that I can work on it.
Maybe, I will purchase a cheap cake mixer.

( All kidding aside, I bet that would work?)
Thanks for offering your advice.
I look forward to your pics of your basement.
