Needle and Thread–Share what you use for what

For most UL purposes(silnylon, grosgrain, etc) I just use a 14/90 needle with 100% poly Gutterman thread. Works like a charm on a 20 year old Singer.

I use 80/11 needle and Gutterman

Thinner needle just so it makes a smaller hole for water to enter

I use near %100 coats and clark thread, both bonded and not.
I have an arsenal of needles, but often find a mid-width 17/135 is good for repairs.

Ordinary poly Gutterman, and the smallest needle I can find locally…for my recent quilt project it was an 8/60 if I remember right, makes for tiny needle holes and NO down leakage.
