I found this after following a link for a 3 year glovemaker's apprenticeship offered by this british company! On their website they helpfully define the different types of seams used, which I remember us discussing a little while back: https://www.chesterjefferies.co.uk/our-gloves/ General Gloving Terms TRANK - The main hand piece of the glove, front (palm) and back. THUMBS - Thumb pieces FOURCHETTES - Narrow strips of leather in between the fingers, sometimes in a contrasting colour. QUIRKS - Diamond shaped pieces of leather at the base of the fingers which provide improved comfort and freedom of movement for the fingers. Quirks are rarely used by other manufactures today. WELT - Thin strip of leather bound over the top (wrist end) of the glove. LINING - Inner glove or part-glove made from fabric, leather or other materials such as Wool, Cashmere, Fur, Lambswool, Fleece, Silk and Chamois leather. Types of Stitching HANDSEWN - Gloves made by hand, the leather is sewn edge to edge with both edges shown. Its takes on average an experienced maker 2 1/2 hours to sew a pair of gloves by hand. Each pair of handsewn gloves has approximately 2000 stitches. PRIXSEAM - Machine stitched, leather stitched edge to edge (similar to handsewn) with both edges shown. PIQUE - Machine Stitched, the edges of leather are overlapped so that only one edge shows. Best used for thinner leather where the glove needs to fit tightly. Typically ladies gloves. INSEAM - Machine stitched, the glove is made inside out and then later turned so that no stitching or edges are visible. WHIPSTITCH/BROSSER - Machine overstitched, the leather is stitched edge to edge but covered by overstitching so the edges do not show.
