Thanks to everyone for your help, I do appreciate it. You're such a helpful bunch! :-)
Joe'smom - thank you, that website is a great resource!
quiltedsunshine - thank you so much for the info. I wondered about the composition as it looked plain white on my screens, but thought it weird they call it grunge if no colors blended in. I have a bit of 108" white paper and it also seems to have some tan-ish color in it, but I will audition it with the red and black once I get them to be sure. will look into grey paper as well. The closest shop that carries Moda is an hour away and their selection was rather small. I truly appreciate your help!
