I used some Martha Stewart papers and ribbon from American Crafts. The fan fold flower is embellished with a pearl brad, and the flag is stamped with a sentiment from Paper Makeup Stamps. It was a freebie during one of the releases. The brads on the drawers are flocked, which gives it some texture.
Unfortunately, I don't have very much 12x12 cardstock so I used patterned paper for the box itself. I would recommend a quality cardstock simply because I think it would be a tighter fit, more snug. But, in a pinch, thicker patterned paper can be used with success.
