Here is an ornament I made from Haas Designs. I love his patterns. This was made with size 30 thread that was given to me by a dear friend. (Hi Lisa!) :D The edging is made with 2 strands of gold sewing thread crocheted together. I changed the edging just a bit from the pattern to suit myself. ;D I used a size 11 steel hook.
