Congratulations, those decals look very good.
My sister learned to sew on a treadle. I had tried once and decided wasn't for me. Then.... my brother and I refurbished it for her. She was very appreciative and said how much she enjoyed sewing on a treadle. I finally got one and played with it. They really are fun.
My sister's is a back clamp too. As much stuff that was in the drawers, there weren't any attachments, but fortunately I had some that I had gotten years ago. I'd like to see what attachments you got with yours.
