This is the $3 tee I purchased on my first ever trip to Walmart in 2010. In nearly two years it hasn't matters what happens to this shirt - it always bounces back. I decided to try rusting with a twist of sorts - the tee was put through the iron mix and caustic soda dip and then placed halfway into the tannin tray - which was made up on a handful of loose leaf tea and a jug of boiling water. Once I was happy with the effect the tee was laid out on the grass to oxidise - complete with leaves. Will be fun to see how it turns out and if it is even wearable!
