I almost fell asleep making a beaded sequin ornament! That wouldn't have been fun to wake up with a sequin pin stuck into my eyeball! :/
One time I made a relatively small order of wedding invites (36) that were REALLY ornate and took forever to make. She picked them up and noticed later that day that one word was missing a letter! We both totally missed it! It was written in a small font, and it was in the middle of the word, so we both skimmed over it. It was one of my first orders, and I had to do them all over at my expense. Now I'm putting a disclaimer that they are responsible for proofreading and final approval of the wording. I, of course, do make sure to spell check, but you never know!
Hope you can resolve your problem and you don't have to re-do work!
