Tools Required

  • Scissors
  • Sewing machine
  • Tape measure

Materials Required

  • 3/4-in. buckle
  • 3/4-in. nylon webbing
  • 3/4-in. tri-glide slide
  • D-rings
  • Lobster Clasp

Project step-by-step (8)

Step 1

Cut the Straps

  • Cut three straps from the nylon webbing material and prevent the nylon from fraying.
    • The neck strap should measure 20 inches.
    • The back strap should measure 10 inches.
    • The stomach strap should measure 30 inches.
  • Note: Measurements are for a mid-sized cat. If your cat is larger, add five to 10 inches to each strap. If your cat is smaller, subtract three to five inches from each strap.

Step 2

Loop Slides Through Straps

  • Loop one tri-glide slide onto the end of the neck strap. Fold the strap over one inch, then sew to the other side of the strap.
  • Repeat with second tri-glide slide and the stomach strap.
    • Pro Tip: You don’t have to stick with 3/4-in. slides. You can use smaller or larger ones. Just make sure you are using the same size for the rope, slide and buckle.
