How do you make beads with Tyvek?
Here is how I make mine:
First paint your Tyvek with acrylic paints or color it some other way (pencils, crayons, etc). Then cut your Tyvek into triangular strips. The length of your strips will determine the size of your bead. Starting with the wide side of the strip, wrap the strip around a toothpick or a skewer - or dowel rod - it just depends how much of an opening you want. Use a drop of glue to hold the end in place. Then either go outside or use a respirator and fire up your heat gun. Heat the Tyvek until you are happy with the appearance of the bead. Let it cool down and remove from the base. Be careful you don't melt it away completely!!
Hope this helps,
