I have hear that about the Tiger Thread. I think that if I am going to pay such a premium for thread I should not have to worry so much about these issues I have head about. I have been using the Crawford waxed linen, 3 ply for making wallets and I am very happy. Also if I have any bigger projects, I am making some motorcycle saddle bags now, I will use the waxed linen from Springfield Leather. I find both to be goo quality and the cost is reasonable.
