Shamanic Rattles –
Made From: Reindeer hide,
Rattle Filled with Shell,
Seeds, Stones.
Handles are either Ash, Hazel or Antler.
Buffalo Horn.
Feathers either Raven, Crow, Seagull, Blackbird, Sparrowhawk,
Buzzard or Pheasant. 
Fur- can be Rabbit, Fox, or Goat.
Bones sometimes used: Bird, Rabbit, Fox, Sheep.
Beads, bone, wood, Nutmeg, Pecan, or other seeds. 
One of the oldest musical instruments, Healing Rattles can be used at the start of Prayer, Healing, Speech, Meditation or Communion with Spirit. No animals are killed specifically for making KH Rattles. Bones, feathers & fur I often gather from field walks, animals that have died naturally or  roadside kills.
Reindeer skin is from Finland, wild culled herds.  Absence of wolves means a rise in herds, numbers that can have deleterious effects on the ecosystem. Yes the meat does end up in the venison trade but majority of hides are discarded. I greatly Honour   the spirit of the animal when using the skin bone & fur I find.          Ash wood Handles are from our biodiverse haven Agroforest here in the West of Ireland, Sheep wool used for the drum beaters is from “Tessa” a sheep who lives nearby with her flock on a friend’s farm also a biodiverse haven, called Cloontabonnive Agroforest.
