Doodling with a Purpose

I'm thinking the next set for my church needs to have a simpler background than what I've done most recently.  No people.  No full range of colors.  So last night I drew up this swirly doodle, thinking I may have this sort of faded in the background.  I think I like it!  I'll probably do more doodles, that way I'll have some variety.  I don't want all 8 canvases to look exactly like each other!
