A premium mecate must be made with premium materials. No matter who makes it, a great mecate can't be made from inferior materials.
Some cheaper mecates have mane hair cover strands, but a tail hair core. This is a serious problem. First, some of those tail hair prickles are going work their way through the cover strands and the rider will feel them. This is minor compared to the second problem. Ropes made this way will self-destruct. Mane hair and tail hair react to water differently. This means when this type of mecate gets wet, the core will begin to crawl out through the cover strands. Nothing can be done at that point and eventually the mecate will be useful only as a wall decoration.
Longer hair makes a stronger mecate. We end up throwing some hair away, but that's a small price to pay for a great product and satisfied clients.
We sort the hair by color and wash it all by hand, rinsing it at least twice to remove all soap residue. Once it is dry, we sort it again by color and shade. We currently have 12 shades of flaxen, 13 shades of sorrel, 13 shades of chestnut, 5 shades of red chestnut, 12 shades of sorrel with white, 13 shades of gray, and of course, black and white. Breaking down the shades so carefully allows us to use complimentary and contrasting colors in unique ways.
