Taking from the very interesting "thick thread problems re backpack 0- tips?" thread, I would like to try to reach an understanding of what threads go with what needles go with what fabrics. I know there are lots of thread threads, sorry about starting another. But as Harold said there are so many people saying 'Gütermann is fine' or Mettler, or DMC, or C&C…
I am confused. Hobbes made the following, very useful comment.
– Quilt seams & hems: M50/M90/1.1 rip (uncoated) – Microtex 70/10 with Gutermann "SewAll" ie Mara 100 (Tex 30)
– Tarp & pack seams & hems: 1.3 sil (1.1 coated) – Microtex 80/12 with Guterman Mara 70 (Tex 40)
– Tarp tie-outs; pack attach points & buckles (shoulder, sternum & hip straps) – Microtex 90/14 with Gutermann Mar 70 (Tex 40)
Sadly the thread names just confused me again.
I own the following threads
– Gütermann polyester, 100Nm

What should I use and for what? The first couple of packs I made I used the Coats Duet thread because it was all I had. It seemed fine, I tried various needle sizes and broke a few of each. I don't know if that was because they were the wrong size or because I was new to sewing.
Last night I tried some of the Gutterman thread above, along with a universal 80 needle. It was awful. After a few stitches the top thread ended up in the fabric as it should be, but NOT through the eye of the needle! I guess it broke somewhere underneath and the needle couldn't bring it back up. That was sewing through a couple of layers of webbing, a layer of nylon and some mesh. Was this just the wrong application? Sewing through just a couple of layers of ripstop this setup was fine.
I was getting very frustrated and gave up for the night. Try again another day.
Sorry for the ramble. If someone could tell me what needle size to use with the three thread types I have that would be a great start. Maybe we can get a comprehensive table together.
