I am sewing long seams on outdoor fabric (flat welt)  and they pucker.  I have the Fabricator sewing machine and use Sailrite thread that was recommended and use a 16 needle, but they still pucker. Could anyone tell me how to solve this?  Even tried changing tension to no avail.

This is called needle pucker and it is normal. Just the fact that the needle and thread penetrate the weave, and then the thread stays in the hole will gather the material along the stitch line. The way to minimize the issue is to reduce both thread and needle size. But I do not suggest doing this at the cost of reduced thread life. My recommendation is to accept the pucker and use a proper outdoor thread in V-92 weight for marine cover cloth. Also sometimes using a double stick basting tape in the seam can reduce pucker as it adds stiffness to the fabric. In general most puckering is not obvious after full assembly of most sewn items. Hope this helps.

Best Regards,
