Soky1972 Report post Posted February 12, 2019 So I've been wanting to start sewing my own small packs so I've been reading and watching videos then picked up a Consew 206rb-5 and added a speed reducer. My next question is my needle selection for sewing bonded nylon into 1000D Cordura and also sewing a little leather as well. Any recommendations on thread and needle sizes/types would be greatly appreciated. Also what is the thin foam backing called that's often used in backpacks and straps that's machine washable?

kgg Report post Posted February 12, 2019 I use ripstop nylon a fair bit and use bonded Coates Dabond polyester rather then bonded nylon. I find the bonded polyester comes off the spool / bobbin more evenly and is less springy then bonded nylon. It is also supposedly has better resistance to UV for outdoor use. I know from experience on my stuff that it does withstand multiple washing in beach and drying then bonded nylon. I would suggest that you try a comparison of both thread types for your stuff and see which thread type works best. Most times I use V69 with a #18 needle but if the stuff also incorporates high density rubber or other material I move up in thread and needle size. What I can tell you is that you will need at least three or four layers of material to give you a nice looking seam. The nicest seams I seem to be able to get is with double fold ripstop binding for the edges. kgg Quote Share this post Link to post Share on other sites
blue duck Report post Posted February 12, 2019 I think the foam you are looking for is called eva foam. It is a closed cell foam that you may find under another name. Quote Share this post Link to post Share on other sites
