My thanks to you all -- Rich, and Box, and sfto1 -- for your inputs.
I think, before I buy any books, I'll take Box's advice and read a lot more of the forum postings, and try the sketchup.com videos, and see what else I can use to learn on the fly.
I don't watch reality TV shows, but I do waste time watching NCIS and Blue Bloods and their ilk. [sigh] I'll try to do better.
Thanks again. If I produce a basic design for my 12x16 meditation room, I'll post it. It won't impress anyone.https://sketchucation.com/forums/posting.php?mode=reply%26amp;f=79%26amp;t=67671#
