This is the heart I made for the Hearts with Wings exchange last month. I wanted to experiment with using different "textures" in the same piece. The split ring lattice work in the center is a technique I learned from Mark Myers.
The silver metallic thread is Oren Bayan on a spool that I got from Lyn Morton at http://www.tatting.co.uk/ It tats very nicely. The blues are Cebelia size 30, shades 797 and 800.
