Hi, I have a new David iii loom and I am a new weaver. Instructions don't include how to attach the apron rod to the back beam. Do I use a special knot? Cord is provided...Jane show how to attach the warp rod to the apron rod which is very helpful in her video from Season 1 about 7"15 seconds in but I don't see how to attach the apron rod. Any help would be appreciated.
Thank you. Jennifer
