For artful paperweights, smooth stones are wrapped with colorful string or felted with brightly dyed roving, which is combed, unspun wool with an exceptionally soft feel.

Choose stones that are any size you like. While small ones make great paperweights, large ones can be used as doorstops.

Tools and Materials
Predyed roving, available at yarn and knitting-supply stores
Stones
Sewing thread to match color of roving

Liquid soap
Warm water
