Yep, admission is the first step to recovery. I am awful at properly packaging and shipping small amounts of cards in plain white envelopes, or PWEs as the kids call them these days, and would love to see a robust comment thread pop up here where people talk about their techniques (max. number of cards/weight, what they use for packing material to protect the cards and stay under the USPS radar, ideal SASE folding techniques for through the mail autographs and so forth). This may be the most dry subject matter I've ever approached on this site, but there are probably others aside from myself who are kinda "stuck" on this, and I know there are some total PWE champions who read my site. So, if y'all would be generous with your various techniques, which I don't think are state secrets or anything, that'd be awesome.
