Gutermann buttonhole gimp is the traditional gimp used for handworked buttonholes. It consists of a wiry core wrapped with very fine thread and provides a smooth, even surface for the buttonhole stitches to rest on. A 1 inch long buttonhole requires 3-4 inches of gimp. Available in white, light blue, pink, orange, leaf green, dark green, bright navy, dark navy and black. Specify which color/s you want and the amount. SOLD BY THE YARD, NOT FULL REELS.
The gimp is covered by the buttonhole stitches so color isn't critical. I've worked white buttonholes over gray gimp and all you see are the white stitches.
