Just a quick idea for paper weaving - for quick, uniform, smaller paper
strips, a pasta manual pasta maker works great! The one I used had several
widths, from vermicelli to fettucini, and worked on several thicknesses of
construction paper at a time. (It's also good for paper mosaics - give the
kids bags of paper strips and let them cut them into small squares.
I even know a teacher who used a pasta maker to roll out and mix sheets of
sculpy, with very interesting results!
