Sewn a bunch of stuff.
You want to get bonded nylon thread, as large as your machine can handle. For the average home use machine 69 is about all the bigger they will digest reliably. Most fabric stores will not carry bonded nylon thread, they usually carry polyester which is weaker. Ralphs Power Sewing at 21st and Bryant carries it plus good needles for your machine.
Don't use a tri tip or cutting needle, use ball point in nylon. You don't want to cut the threads of the fabric and that is what a sharp cutting needle will do. The ball point pushes the threads of the fabric aside and your seams will be stronger.
Thread tension is critical with the nylon thread, too tight and the seam will pucker and too loose the seam is weak. Some home machines may have a hard time pulling enough tension on heavy nylon thread.
About 10-12 stitches per inch will work well on packcloth.
Bar tack the beginning and end of each seam 3-6 times.
Don't bother trying to pin nylon together, your fingers will not be happy. Staple it instead, just use one leg of the staple through the fabric and after the seam is run straighten that leg and carefully weasel it out from under the seam.
