Tackle Twill, or applique, involves sewing down a number or letter made by cutting pieces of one material and applying them to the surface of another material usually with a nylon twill. Basically, tackle twill begins with a "patch" of sorts that is applied to the jersey, shirt, hat or other garment that is then sewn to the material for a more rugged finish.
Tackle Twill is the most popular for both professional sports teams and school athletic organizations. Look closely at your favorite football, baseball, or hockey player's jersey. Also look at many of the jerseys fans wear when watching the game. These jerseys have most likely been decorated with tackle twill names and numbers.
Advantages of Tackle Twill: This type of applique offers a bold look to your uniform or jersey, but the stitching count is lower than embroidery, thus is more affordable while creating a three-dimensional work of art.
