When I did it in DMC gold it came out 1.25 inches across which was just a bit small. So I had to re-do it again larger.
Here is the larger version entwined with a second heart and some gold embroidery on a satin backing and mounted in a 5x7 frame. We had a 40th wedding celebration for my sister Flo and her husband Allan, yesterday. I wasn't present when it was unwrapped so I have not idea whether they liked it or not. They probably did. My siblings are all wonderfully supportive.
In case the reflective thread makes it hard to read, across the top it says Faith Hope Love

DMC gold embroidery thread is the pits to work with especially on slippery satin. I tried working with 6 strands which just threatened to pull holes through the fabric so I switched to 3 strands. That still didn't work so I resorted to the spooled metallic gold that I used for the tatting. It worked better but I could only do 4 or 5 letters before the thread unwound and became impossible to work with.
In comparison, Gale Marshall at Tat's All carries a gold thread that's a dream to work with for many applications.
