I let my kids loose with the brown paper-wrapped packages we were sending through the mail. Each previously boring package now hosts a party of stickers, doilies, scribbles, drawings, and sequins. I wasn't sure of their reception at the post office, but the lady there didn't bat an eye. I guess they'll go through okay. I did add a layer of packing tape and/or transparent contact paper over some areas of sequins or stickers that I thought were in danger of falling off en route (wouldn't want that to happen!).
