In a production series, the number of items each having a different visually detectable feature provided before said visually detectable features repeat themselves is greater than the number of items imparted after one full turn of the roll. Also disclosed is a package including a plurality of items each having a visually detectable feature that is different from the visually detectable features of all other items within the package, such that a first item includes a first visually detectable feature, and a second item includes a second visually detectable feature including at least a portion of the first visually detectable pattern element, wherein the first and second visually detectable features are different.
