You can have the best of both worlds: the look of traditional sewn on letters and the value of a lower retail. The Sim Stitch letters are real 2 layer twill that has been delicately etched with a laser to simulate a zig-zag stitch, giving the look of traditional sewn on letters. Eliminating the stitches allows for a lighter decoration adding extra comfort to your cotton long sleeve tee with rib knit cuffs.
