Century Dictionary and Cyclopedia

1. To weave in a particular way (see twill, n.), producing diagonal ribs in the stuff.
2. n. A variety of textile fabric in which the weft-threads do not pass over and under the warp-threads in regular succession, as in common plain weaving. but pass over one and under two, over one and under three, or over one and under eight or ten, according to the kind of twill. The next weft-thread takes a set oblique to the former, throwing up one of the two deposed by the preceding. The effect of this is to produce the appearance of parallel diagonal lines or ribs over the whole surface of the cloth; but the regularity of the parallel lines is broken in various ways in what is termed fanciful twilling. The goods so manufactured are stronger than those made by plain weaving. In twilled cloth the number of heddles used is equal to the number of threads contained in the interval between two intersections of the warp and weft, as when every third thread is to be interwoven three leaves are used, for six threads six leaves, etc. Twills are called, according to the number of leaves employed in the weaving, three-leaf twill, six leaf twill, etc.
3. n. The raised line made by twilling.
4. n. A reed; a quill; a spool to wind yarn on.
5. To quill; trim with quilling or fluting.
6. The great fat pincushion lined with pink inside, and twilled like a lady's nightcap.
7. A dialectal variant of till.
