If you are familiar with Paul Carnazzo's excellent Lookout Wallet,the handling is exactly the same
even though this uses a different principle for the p***. (Part of the working depends on an old
Annemann idea. I love how the old ways still hold up.) I wouldn't say that it's particularly
difficult to make, just tedious, so the less ambitious will probably just splurge for the leather
wallet. While I love Carnazzo's Lookout Wallet, this may actually be more deceptive since it looks
so unassuming, like a stack of ordinary business cards. As a bonus, you can use it for the OTL
principle, something you can't do with the wallet. Get the more expensive package, not the instant
download, and save yourself the hassle of searching Amazon for the one non-common item that you'll
need to complete a really excellent DIY mentalism utility.
