November 2019 Update: Wow! Taking existing patterns, creating a couple coordinates to go with them, and creating presentation sheets takes time, more than I thought. I have about 18 done and they're taped to my wall so I can see my progress. Here's one that I recolored. The coordinates are totally new.
I have officially signed up for the show so it's 'do or die' time. Oh, I've found out that I stink at creative naming. Lol.
