    DiprylA textile that feels like a cross between paper and fabric. 
    Seam AllowanceSeam allowance (sometimes called inlays) is the area between the edge and the stitching line on two (or more) pieces of material being stitched together. Seam allowances can range from 1/4 inch wide (6.35 mm) to as much as several inches. 
    Fabric ScissorsLong bladed scissors that are sharper than normal so that fabric can be cut without rips, tears or pulls. 
    Pattern PaperShapes drawn on thin paper that when cut out and pinned onto fabric create a template for pieces of a garment etc. 
    TextilesA textile or cloth is a flexible woven material consisting of a network of natural or artificial fibres (yarn or thread). Yarn is produced by spinning raw fibres of wool, flax, cotton, or other material to produce long strands. Textiles are formed by weav
