The tailor has been sent to hell for cheating a customer by skimping on the amount of material he used to make a pair of French hose, a type of fancy stocking. But Shakespeare’s choice of words suggests a different interpretation—that an English tailor has cheated a French customer.  This wordplay would have amused King James and the other Scots at his court. Among the English, it was a standard joke to portray the Scottish as dishonest; this clever wordplay reverses that stereotype.
