A dent is a single vertical slot in the reed of a weaving loom. The weaver threads one or more warp yarns through each dent to keep them evenly spaced and parallel across the width of the fabric. The density of the fabric is determined by the number of dents per inch in the reed and how many threads are sleyed into each dent.
Heard on the job
Sley two threads per dent to get the right warp density for this twill pattern.
Insider tip
A reed rated at 10 dents per inch can weave a 20 ends-per-inch fabric if you simply double up the threads in every slot.
