Sorry you had a bad experience shrekfest.....I have used them for years and sold hundreds of sheepsking they have cured for me and other local farmers. They HAVE to do the hole punching in the armpit skin or they have no way of knowing yours from hundreds of others
.....its a unique code.
Also just how huge are your skins if 4 weigh 25kg
You do have to be careful what you send in and when, for example great big long wool skins can be difficult to process if the wool is too long, ideally it should be about 3ins max so shesr first then grow out the tramlines and then kill.....even with lambs.
Also never try and cure skins between Dec and June as they tan poorly due to the new fleece growing and a weakness occurring leading to wool break.
