I use Tri-angle paper or Tri-angles on a roll for making HST's. The paper is a lighter weight than copy paper for the roll and a newsprint paper for Tri-angle paper and both tear off easily. Just make sure to use a smaller seam allowance than normal. To tear off the paper, I put my thumb in the middle of the seam allowance and tear off the large piece of paper. The seam allowance paper then comes off easily.
