This is the original Athalia design:
I am pretty sure the thread is Yarnplayer's 'Peace."
This is the one I completed tonight:
Originally, I designed this after the Misha heart last year, using the idea of rings in a semi-circle around four corners.
I do not have the little round doodad, so I used the same one I used on the Misha heart, as I have a few of those. This changed the outer shape somewhat, so I have to re-tat it and change the count...
Tomorrow I shall write up a final draft of the pattern.
