“You are my Sunshine” Tooled Leather dog collar. This super high quality collar features hand buckstitching. Buckstitching is a technique used in leathercraft for securely joining two or more pieces of heavy leather along a seam. ... The chisel is held over the leather pieces to be joined, and is then struck with a mallet until the chisel penetrates all of the leather and produces what are called lacing slits. The lacing on this collar is done in a complimentary turquoise leather “lace”. Available in four sizes: Small 46cm (18.11”) Medium 57cm (22.44”) Large 68cm (26.77”) XL (31.75”)
