A method of producing a non-slip patterned sports ball includes the steps of: (a) thermal-pressing a transparent sheet and a covering sheet together within a mold having an embossing surface so that anti-slip protrusions are formed by the embossing surface on a surface of the transparent sheet opposite to the covering sheet and so that the transparent sheet is adhered to the covering sheet; (b) tailoring each of the transparent sheet and the covering sheet; and (c) sewing the covering sheet around a ball bladder, thereby covering the ball bladder.
