Sometimes you see woven polythene sacks which are excellent for
disposing of nasty spiky stuff (keep the bags!). These look like
normal material which has been heated and flattened (like a
modern tent groundsheet). If you chop your thorny twigs up small,
they become far easier to handle - it doesn't take long, either.
