The traditional buttonhole gimp used in handworked buttonholes. This is Gutermann agreman No. 1, which is a wiry core wrapped with very fine thread. The gimp provides a smooth, even surface for the buttonhole stitches. A 1 inch buttonhole requires about 4 inches of gimp. Available in 12 colors. Pictured from top left: white, light blue, pink, orange, burgandy, denim blue. Bottom row from left: leaf green, dark green, rust, dark brown and black. The buttonhole twist is covered by silk buttonhole twist, so getting an exact color match isn't critical. I've worked white buttonholes over gray gimp and you can't see the gimp. Sold by the yard.
