I saw on the Specialty Outdoors web site that you recommend an
80 or 90 needle for sewing silnylon. Before reading that, I would have guessed a 70 Microtex Sharp, since it's such a fine fabric. Just so I understand, how do you decide on which needle for such a fabric? (The engineer in me needs to know these things).I just got a bunch of sky blue silnylon to make a tarp. Gorgeous colour!
