if you're a child or wedding photographer and looking for some cute, trendy ways to package stuff (be it for presentation or mailing), check out
nashvillewraps.com. their pricing on bags, boxes, etc. is really great.
i package all my proof sets in tiffany blue boxes, and found some great (and very inexpensive) little blue and brown polka dot items that work great with them.
i also made notecards out of several of my prints, and found some cute boxes to package them in.
if you are more into the leather and faux-leather stuff, this isn't for you ;)
