Typically it's taught that there are two accounts related to Supplies; Supplies (Asset) and Supplies Expense (Expense). When you purchase Supplies you'd Debit the Supplies (Asset) account and Credit Cash or Accounts Payable. When you use the Supplies, you'd Credit the Supplies (Asset) account and Debit the Supplies Expense (Expense) account.
Hope this helps!
