Weaving of fabrics on 4 harness loom
Presentation of some difficulties and their solutions
To do a fabric, thinking of making a coat, I prepared a warp with a length of 4,50 m. All of the threading I present were done with chairs around a table, always following the crossing, to facilitate later the setting up of the threads (the order is preserved and tangles are avoided). I calculated the length and made as many rounds as needed. I used a 50/70 reed, this means I required 350 threads + 10 (always double on the edges), from which 40 were black.
While rolling up, I placed paper so that the roll of warp remained even.
A look at the distribution of the threads, it allows seeing if each slot has a strand, and if the distribution of colors is the one wanted. After rolling the fabric forwards, I started knotting the threads on the warp roller.
Finally, I rolled the warp backwards so that the threads stayed firm, tight and even. I checked once again to make sure the warp was placed correctly. When opening each shed (lifting each heddle separately), it is immediately evident if a thread isn’t in the correct order.
I had a few surprises.
First difficulties: crossed threads
After correcting the mistakes, I tested the 4 sheds again, until I made sure that no thread was crossed, both ahead and behind the heddles.
This type of warp allows making different designs on the fabric, depending on the treadling you choose. Using two different colors for the warp and a different color and yarn for the pick, gives the following result.
Second difficulties: Knots in the warp
In this link you’ll find how to solve the problem of finding a knot or break in the warp.
Almost reaching the end, I change the color of the pick. This part of the cloth can later be used for details.
I’m finishing the fabric and you can see at the end of the warp an “additional warp”, which can be used at the beginning and end to take maximum advantage of the original warp’s length.
…and I start closing with the Peruvian knot from one end to the other, making sure I take all of the strands from the warp.
