Thanks for all the help so far, I feel like I'm learning a lot.
One point of confusion for me still is how to properly pair needle size with thread size. A few of you have suggested using a "denim" specific needle, which I take is in the 90/14 or 100/16 size range. Meanwhile, others have suggested using a lighter weight thread for ease of sewing…
But now I read online that pairing the size of needle with the size of thread is very important for getting a nice end result and smooth sewing. This implies that the heavier "denim" needles will require heavier thread, and the lighter needles will need lighter thread.
Which one should I go with? Also, should I be using sharp needles or more rounded needles?
I'll be sewing through 210 denier double ripstop nylon (pack body), nylon webbing, and maybe a little bit of 600 denier polyester (pack bottom), though not necessarily all of those things together at once.
Thanks again for all your help!
