Straighten the tassels: Since these tassels were stored for decades, they are fairly crumpled which is a cinch to fix: moisten the tassel with a squirt of water and hang it up by the loop to dry - the strands will straighten within seconds. That is all there is to it! .
Shorten the tassels as needed: Spray with water, place on a cutting mat, position a ruler over the ends and cut them off with the roller cutter. Let dry.
