Musar על סנהדרין 215:1

Nowadays, the iniquitous practice of stealing [the leftovers] has become very widespread among the tailors. Through this they commit two evils: First of all they spoil the garments they make. Secondly, they violate the commandment against stealing, behaving as if it were permitted. They do not even take the matter seriously enough to feel regretful about it or to make confession over it, having become so accustomed to it. They do not realize the severity of the punishment that awaits them. Therefore I admonish every tailor who has stumbled in this sin: Let him repent and take it to heart to return to the owners what he has stolen or else to do something on behalf of the public. For it was only on account of theft that the fate of the Generation of the Flood was sealed (Sanhedrin 108a). I know of one tailor in the holy community of Brisk in Lithuania who instructed the Burial Society before his death that they should construct his coffin out of his work-table and place his measuring stick in his hand. When they asked him the reason for this request he explained that his work-table and yardstick were his two faithful witnesses that in his entire life he had never stole even one piece of his working materials. Fortunate is he for wishing to benefit only from the work of his hands and not from theft.
