For the last several years, I have used Tandy's 346 white waxed nylon (?) thread, . . . with almost no problems at all.
The one situation I cannot fix is the thread will not take dye permanently, . . . it eventually rubs off, . . . and generally turns some color between white and the product dye color.
I'd like to find the same thread, . . . in brown and in black.
I bought the offering Springfield Leather had to offer, . . . was very much disappointed with their thread (but to my pleasure they offered to take it back, . . . full refund
).
Anyway, . . . it is a heavily waxed thread, . . . wonder if you all know where I can get something equivalent.
May God bless,
Dwight
