I've yet to discover the perfect type of thread for hand sewing. The Al Stohlman book recommends cotton or linen, waxed. I bought some waxed linen thread from Tandy, and the problem is, it breaks all the time. About every 8 to 10 stitches, in fact, it breaks right at the eye of the needle. It gets very, very frustrating having to stop every 5 minutes and rethread my needle, especially since the thread gets a few inches shorter each time.
I looked around and found "synthetic sinew," which appears to be waxed nylon. The good thing is, it doesn't break. The bad thing : It's so slippery that knots won't hold. With the waxed line, I used the method of piercing through the thread with the needle, then bringing the end of the thread around to the eye and pulling it through. This makes a larks head in the middle of the thread around the needle. That holds the waxed linen in place, but the synthetic sinew just slips out. I've tried almost every knot I can think of, from a few half hitches, overhand, square knot, etc, and any knot that's strong enough to hold is so big it doesn't go through the holes.
Sewing is turning into the part of any project that I dread, and I find myself procrastinating. I love how the finished product looks, but these problems are making sewing an exercise in frustration. Any tips? What thread do you guys prefer, and what knots do you use to hold it in the needle?
