I have long rejected the idea of a duct tape wallet because of the sticky residue that duct tape will leave. However, in my quest for the perfect wallet I fear that I will have to turn to DIY measures and a tape wallet can be assembled easily for a prototype. One forumite recently suggested using gaffers tape over tyvek to keep it from wearing out. I looked into gaffer's tape, and it sounds like an ideal material for such a task. Unfortunately, no one ath the local hardware stores seems to know what it is. Are there any nationwide hardware or retail chains taht stock gaffer's tape? :shrug: Here are some of the chains in my area: Advanced Auto Parts AutoZone Home Depot (every department swears they don't have it) Lowe's Micheal's O'Reilly's Sam's Club Target Walmart I'm open to other suggestions, but we don't have a Costco anywhere around here.
