<< I plan to tie dye T-shirts with my 5th graders. >>
Rubber bands, big ones, small ones, overlapped ones, the thick ones that come
on broccoli! You can never have enough rubber bands for tie dying. Also, my
lovely maintenance man gave me a "bucket 'o garbage ties" that work great
too. The ones that are notched, and one can tighten well without leakage.
Hope this helps.
