Hi Susie,
Thanks so much for educating this construction challenged gal! :D No need for you to have used the red faced emoticon, but it was cute, lol. This is just one area that I haven't had any experience in, so I'm starting at the ground floor, you might say.
Gosh, how nice to know that there are ways to get some discounted drywall and paint. Again, I was clueless. I'll let DH know. He'll be pleased. Thanks so much. Karla
