Description from book:

“This durable chew toy is a great homemade gift that looks a lot like commercial rope bones sold in pet stores. Knit with Poly Utility Cord, easily found in your local hardware store, it’s a quick project that can be completed in one evening.

Three sizes are provided, but the pattern makes it a cinch to improvise. Knit the bone as long or as short as you like; just remember to leave room for the knots at the end. Is your cord thicker than the one specified? Great! You’ll end up with a thicker bone your pup can really sink his teeth into.“

Size:

length 6(12, 14) in or 15.2(30.5, 35.6) cm
