If you have a bottom spring kit, as I do here, start weaving your header. If you don’t have a bottom spring kit, cut a thread three times the width of your loom. Engage the shedding device, weave it to the threaded bar, wrap it around the threaded bar, change the she and weave it back to the other threaded rod. Tie the two ends tightly around the threaded bar. This will serve as a base for starting your weaving. Make sure the two threads make a straight line. Arrange the warps so that they are evening spaced at ten ends per inch. Then begin weaving a header.
Next, weave the left weft to the right but weave over one more warp. Do the same for the other three wefts. The goal is to create a diagnol shapes by weaving over one warp when you go to the left and reducing by one warp when you weave to the right.
Follow the pictures. Your left shape is gong to get bigger and bigger whereas your right shape is going to shrink.
At some point you can remove the guide threads as they won’t be necessary.
To end the left weft wrap around the end warp so it is hanging to the back.
Weave back all the other wefts.
Stick the ends of the other wefts to the back of the piece.
Insert a new silk weft.
Weave it for a few passes.
Add a second weft to the existing weft that is longer.
Weave until you run out of the first silk. Replace with a new silk weft to add to the existing weft.
Weave until you run out of one of the silk threads and replace with railroad yarn.
End the railroad yarn and replace with silk weft.
Weave a couple of rows of silk weft.
