One of the best and safest items to make a bird toy with is Superior Poly Rope. This durable rope is bird safe and makes any bird toy a breeze to make.
The unique twist of this Superior Poly Rope prevents unsafe lengths of fray. Also, polyethylene fibers do not have a "memory" like other rope; this prevents entrapment and limb strangulation caused by fibers such as nylon.
Supreme Cotton rope is one bird toy part that birds truly love. It is 100% natural and unbleached. Supreme Cotton Rope is short fibered and, therefore, pulls apart easily, which will minimize the risk of entanglement. If your bird pulls on the fibers from the ends or shafts, you will get cotton puffs instead of long threads.
