With Turned Monk’s Belt both the background and the pattern threads are contained in the warp and this weave thus requires only one shuttle to weave the weft.  The pattern will appear as vertical stripes in the finished towels.

I’m using up my stash on hand, so for the background, in 2/8 cotton, I chose a rust colour.  The pattern threads will be some autumn coloured 2/8 cottons.  I think this will represent Autumn well.

Here is the yarn wrapping for the stripe colours

The towel will be plain weave in the background colour, rusty red, and there will be two vertical strip sections in Turned Monk’s Belt.  Sett at 20 epi for the plain weave sections, (borders, Centre and 10 thread sections in the stripe) and 40 epi in the pattern sections.  Thread the coloured pattern threads in the same dent as the corresponding background thread, but through separate heddles.  The background threads are on shafts 1 and 2 and the pattern threads are on shaft 3 for Block A and Shaft 4 for Block B.

The profile draft for the stripe sections is:

And the colour order for the stripes is:

The threading plan will be:

Border – 50 ends background; Stripe section – 82 ends background and 62 ends pattern; Centre – 140 ends background; Stripe section -82 ends background and 62 ends pattern ; Border – 50 ends background

And the tie-up and treadling.
