Part 3 of E. A. Posselt's serial on fabric analysis, from the January 1911 issue of Posselt's Textile Journal. It covers ascertaining the weave of a sample by picking-out: point paper (8 x 8 ruling) and how to mark risers and sinkers, preparing napped or felted samples by shaving or singeing, and telling warp from filling. It then gives step-by-step instructions for loosening picks with a needle, recording each pick's interlacing on point paper, and finding the repeat. Two figures show how to cut and prepare a sample and how to hold it while picking out a filling thread.
