Seriously? What nerve! I can't believe that this has happened to you. Discount, shmiscount! You had a verbal agreement with her for $125 + cost of materials. That in itself was a steal. I learned a long time ago to get a deposit on projects. No project is too small for a discount. Unfortunately good faith has gone down the toilet. You can hold it hostage until she pays you the full amount agreed upon or you can hang it somewhere and enjoy it or you can sell it to someone else. I'm sure if you put it on ebay or craig's list, you'd get a buyer for more than your requested amount! Good luck. Please let me know if you do any of the following.
