In the Alabama Chanin method of sewing, using a double strand of thick button craft thread with cotton jersey fabric, we always use a double knot. Many people have their own way to tie a knot. Years ago when I traveled back to the Alabama Chanin Factory, I was shown this method of tying a knot. It immediately became my favorite! When I demonstrate this method in class, I often see light bulbs going off, just like it did for me that day at the Factory. Here are quick tutorials on how I tie my beginning and ending double knots. Use your pause button, because the words flash by fairly quickly. Be sure to lock in those knots with your nails and a tug. I hope this helps!
