Italian to English Other Textiles / Clothing / Fashion

It's talking about a linen garment; I'm unsure whether they're referring to a pencil sketch that serves as the inspiration for the weave, or referring symbolically to the grid of the linen on the actual garment as resembling a pencil drawing/sketch. Here's the passage, for a children's clothing website:

"IL LINO A RIGHE
Il lino non è semplicemente a righe: avvicinandosi con lo sguardo non sfugge l’irregolarità del tratto a matita, la diversità tra una striscia e un’altra. Si tratta infatti di una stampa che nasce da un disegno realizzato a mano con estrema cura e attenzione: un dettaglio di unicità e autenticità."

Here's what I have so far:
"Linen is not simply striped: when you look at it close up, you can't miss the irregularity of the pattern, the difference between one strip and another. This is a print made from a drawing made by hand with great care and attention: a mark of uniqueness and authenticity."

Thanks for any help on this,

Peter
