To fray jeans, cut the hems, scrape the hems with scissors and sandpaper, and put the jeans in the washing machine and dryer. Cut off any loose frays that are too long.
- Cut the bottom hems
Lay the jeans on a flat surface. Cut all the way around the hemline on both pant legs.
- Scrape the hems with a pair of scissors
Hold the bottom of the pant leg sideways, and firmly grip the bottom of the jeans. Open your scissors wide, and scrape the scissors across the hem with short, quick strokes. Flip the hem inside-out, and scrape the other side of the hem. Repeat on the other leg.
- Scrape the hems with sandpaper
Place a sandpaper block on the hem, and quickly rub the block back and forth to give the denim a weathered look. Repeat on the other leg.
- Wash and dry the jeans
Put the jeans in the washing machine on a cold setting. When the jeans are done washing, put them in the dryer on a warm setting. The motions of the washer and dryer create more fraying on the jeans.
- Cut overlong strands
Use a pair of scissors to cut any strands or frays that are too long.
