Greedoniz,
you don't actually need Tyvek to practice the switch with, just use normal paper. Sankey recommends Tyvek because it can be reused over and over in performance. However if you want to get the moves down, normal paper (eg cut to the size of a bill if you want to do blank to bil, or 2 blanks if you want to do Fan Mail)
Good luck and remember to get it very smooth before you go and practice it.
