Update, I finally decided on white and spent the rest of the day working on the layout. It doesn't look like the kind of layout that would take all day to complete, but the sewing, pulling threads, tying them and taping them down took forever!
Anyway, here is the final product.
I'm puzzling over what to do with this layout.
I picked up the design from an on line sketch and I really like the blocks. But I'm not sure what color I want for the background.
I thought I liked the brown until I took a photo (after arranging the papers so I could put them back when it came time to glue everything down) and saw the thumbnail.
