Cheryl, I'm replying in this awkward way because Thunderbird went haywire and I had to re-establish everything.
My wool-on-wool necessary's initials were done in teeny chain stitches, not French knots, with a single strand of Appleton crewel.
Good luck in your project for your DD. I was always going to take my project apart, line it, cut down the seams. But I never got to it. Once done, once forgotten. It served its purpose. I've decided not to design for awhile. Other fish to fry.
