Baseballs are hand-sewn, and there are a total of 216 stitches on a ball. Each stitch is double stitched, and the first and last stitch is hidden.
They are stitched by hand using 108 stitches taking about 10 minutes. Once stitched, the ROMLB’s are machine rolled for 15 seconds to flatten the stitching. Then the Rawlings trademark, MLB logo, and commissioner’s signature are stamped on the balls and allowed to dry for one week.
In 1934 the MLB adopted a league-wide standard which has gone largely unchanged today: 108 double-stitches of waxed red thread.
Each baseball’s stitching is sewn by hand using 88 inches of waxed red thread. It takes about 15 minutes to hand sew the two figure eight pieces of exterior cowhide together before passing the baseball into a rolling machine for 15 seconds to level any raised stitches.
