Holes can develop during all the stages of parchment production. In most cases, the holes develop when the parchment is stretched.
Mechanical damage tends to occur easily during the final stretching and scraping. The most frequent types of damage include cracks and holes, which were often repaired by darning in the process of producing the parchment.

Auk.
Augud võivad tekkida pärgamendi valmistamise kõigis etappides. enamikel juhtudel nõeluti need augud koheselt kinni. Pärgamendi edasise venitamise käigus võisid parandused sageli lahti rebeneda. br>
Holes can occur at all stages of parchment making. in most cases, these holes were immediately stitched up. During the further stretching of the parchment, the corrections could often tear apart.

Augud ja lõhed võivad tekkida pärgamendi valmistamise kõigis etappides.
Levinumad kahjustused on lõhed ja augud, mida pärgamendi valmistamise käigus sageli ka nõelumisega parandati. br>
Holes and splits can occur at all stages of parchment making.
The most common damages are splits and holes, which were often repaired with needling during the process of making the parchment.
