Basic Project No. 4 from Terrace Textures gives instructions for handwoven cotton aprons in two types: Type I is woven across a wider warp, and Type II uses the warp width as the apron length. It includes tables of yarn amounts, warp lengths and sett, a four-shaft threading adapted from Weavers' Fancy, and weaving and treadling directions for six aprons with suggested colors. The last page gives general directions for washing, sewing belts, gathering and hemming the finished aprons.
