I agree. The blue set of Monograms I showed were from ladies sewing website not from anything Mason Co. used. I knew that the letter Robert called an "O" was really an "I". I recognized that little phantom line from things Gene had told me. What I was talking about was how the Letter "D" can be confusing, especially in that first position. It does look like an "O".
Do we have that Marquis shaped monogram with the letters in every position as a guide somewhere?
