I was just kidding with you Bruce. Ivy's are climbers, and if you, as most, are susceptible to the oil's causing, well, your condition, cloths wont help. The oils only have to come in contact with fibers and they will wick, or saturate a very small spot, especially if it is cotton. Add perspiration, humidity and general motive animations like the Condello Technique and your cloths will move, and those nasty oils are still in one spot, but moving as you do, so it spreads.
I hope I did not over complicate this issue.
