Tried and True: Weft Rep

The monksbelt piece that adorns our entry is my favorite from all the projects in The Big Book of Weaving, by Laila Lundell. This current narrower version on the Standard is another heirloom monksbelt piece in the making. The ground cloth is weft rep.

Multi-color ground weave and vibrant Fårö pattern colors make this monksbelt fabric a standout. Glimåkra Standard in the background holds a new version of this favorite piece.

This is snail’s-pace weaving, with 2 picks of 16/2 cotton for the ground weave between every 6/1 Fårö wool pattern pick.

“To weave [weft rep]…the weft must be longer than the width of the warp and so the weft has to arc across the shed. There are two ways to do this: with many small waves across the width or with a large and high arc…The tiniest bit of unevenness can quickly build into hills and valleys across the weft line…”

Weft Rep in Three Steps

1. Make a Mountain.

After throwing the shuttle, increase the length of the weft by making it into a large arc in the open shed. Put one finger through the warp to form the peak while keeping enough tension on the thread with your other hand to maintain a good selvedge.

2. Make Hills and Valleys.

Keeping the shed open, push the mountain down into hills and valleys to evenly distribute the extra weft.

  • Turn the mountain into hills and valleys with your finger.

  • Simply drag your spread-out fingers lightly through the weft.

  • TIMESAVER – Slowly pull the beater toward you (shed open), smooshing the weft into a wavy line. Stop two or three inches away from the fell line.

3. Flatten the Hills

Treadle for the next shed. On the closed shed beat in the weft. Two short pulses with the beater distribute the weft more effectively than a single squeeze with the beater.

Watch for little loops that may form in places where there is a bit too much weft. To correct, open the shed, pull that portion of the weft back into a little hill and redo.


  • TIMESAVER – Draw the back of your fingernail across the warp where you see excess weft. This is often enough to even out little bumps.

Slower weaving develops into a rhythmic pace that is comfortable. And the cloth grows, line by line.

  1. Hello Karen,

    This is absolutely stunning! I have been thinking about trying Monk’s belt for a rug and you have inspired me.

    Take care,

  2. Thank you so much for these instructions. I’ve struggled to avoid those streaks that show up when the weft is not consistent and am looking forward to following your method on my next monksbelt project. Your excellent craftsmanship is always an inspiration.

    1. Hi Joan, We’re in this together. I’m so glad you could learn something here. I’m constantly finding out that there is so much more for me to learn–it’s never ending. That’s what I like! The weft in this newer monksbelt is much more consistent than the big one in the first picture. However, I don’t think anyone has ever noticed the inconsistencies, except me. 🙂 Thanks for your very kind words.

      Happy weaving,

  3. Thank you for these instructions. I have been spinning some very coarse wool that I am planning to use to weft face small rug. Do the floats hold up or do things get snagged?
    I love all of your colors-makes me feel happy!

    1. Hi Tobie, I’m glad you’re pleased with the colors. Colors are such a joy to work with!

      If you weave a piece that is purely weft faced, you shouldn’t have any problems. The weft threads will be packed in very close together. For the monksbelt I have on the loom, only the ground weave (16/2 cotton) is weft faced. The ground weave doesn’t have any floats. The monksbelt pattern in Fårö wool does have floats. Even so, I haven’t noticed any problem with snagging at all. The quality of your yarn should determine that what you weave will hold up over time. Your handspun should make a very nice rug!

      Thanks for asking!
