Reed Substitution Chart

Reed Substitution Chart

Generally, it is best to aim for as few threads per dent in your reed as possible. More than 2 or 3 ends in each dent can leave reed marks in your cloth that will not come out with wet finishing. Eventually, you will want a selection of reeds to choose from. A 12 dent reed is the most flexible reed and an excellent reed if you have only one. As you gain experience and want to add to your collection, an 8, 10 and 15 dent reed will allow you to weave well at almost any sett.

Your reed can also be used as a design tool. Purposely threading your reed more densely in some areas and less in others can create a variegated cloth where the spacing becomes a design feature.

This chart is designed to assist you in determining the best way to sley your reed to achieve a given sett. See the following examples in order to best understand how the Reed Substitution Chart works.

You want to weave some 8/2 cotton tea towels at 18epi, but you only have a 12 dent reed.
Sley your reed 1–2, 1–2, etc. This will give you a total of 18 epi using a 12 dent reed as consistently as possible.

You want to weave a rug with the warp sett at 8epi, but you only have a 10 dent reed.
Sley your reed 0–1–1–1, 0–1–1–1, etc. This will give you 7.5 epi which is close enough to 8. You may notice subtle streaking in the spaces with no thread. The streaking often becomes less visible after wet finishing.

Delicate yarns that can break with abrasion in the reed benefit from a more open reed.for example. a 10 epi nubby wool warp would prefer a 5 dent reed to a 10 dent reed.
