The February 1959 issue (Volume XXXVI, No. 2) of the Shuttle Craft Guild's monthly bulletin, Portfolio Edition, devoted to man-made fibers for handweavers. It covers burning tests for identifying fibers and weaving experiments with Fiberglas, Cuprama, Saran and aluminum strips, with warp and weft details, sett, and sample notes. Mary Black's experiment with a crackle draft in rayon, nylon and other yarns includes drafts and treadlings, and there is a cotton and rayon check for dresses and a lamp shade material record. The issue also has guild news and round robin letters, a book review of Black's tartan booklet, a book list and advertisements.
