Mark the front of your reed with dots that correspond to the location of the strings on your beam stick.
1) Put your fingers through the loop at the cross.
2) Put your thumb in the space created behind the cross. Give a slight tug to even it out.
3) Remove the loose tie at the cross and the one just behind it. Leave the tight choke in place.
You can now work while holding the warp chain. Just use the crook of your thumb to hang on to it.
Remove the beam stick from the strings.
Remove the top thread at the cross between your thumb and fingers from your hand. Make a loop with this thread and hold it between your fingers. Grab the loop with your hook and pull it through the starting slot on your reed. Put the loop on the beam stick. Continue across your reed until you come to a dot on the reed. When you come to a dot, stop putting warp loops on the stick. While holding on to your warp chain, place the string that's on on your warp beam onto the beam stick and then continue warping.
You are now ready to begin the beaming process. Grab the warp at the TIGHT choke next to the reed and give a slight tug to even out the threads on the beam stick. Once they're all even, remove all the remaining ties except for the very last tight one. Tie the end of your warp into a single overhand knot. This keeps the ends from becoming grossly uneven.
If you run into what appears to be tangles, simply keep tension on the warp and strum it like a guitar and/or flick the strings. It is not tangled in the conventional sense so, resist the urge to comb it. As you wind onto the beam you'll find that everything will straighten itself out.
