Is a horse supposed to have a certain number of plaits for showing? I usually do about 10-12. May sound like a silly question but its something that has never crossed my mind before.
As many as suits your horse's neck and mane. I think it's traditional to have an odd number along the neck, plus forelock, but do as many as look good (but not about 30 for instance!!)
Do you mean the comb that splits the mane in 3? They aren't much good if you do as every horses mane is a different thickness and you end up with odd looking plaits
As already said, depends on the horse! If te horse has a long neck, try to put less plaits in, short neck, lots in, helps balance out the illusion. Also bigger "high" plaits will make the topline look more. My Boy gets about 18-20 plaits as I like little neat ones, and he has a short neck!!
yeah 7 or 9 in neck then top knot to make even. To make it fit you can take out more or less mane when clipping withers and poll. Plait width to be no more that comb width. Plait damp and not to clean a mane for best results
