I made this because the Breeze "pin" icon looks like a location pin, not a thumbtack like would be used to e.g. mark a featured post or something. Hopefully it's pretty close to the style of the Breeze icons. It uses the mirror symmetry modifier in Inkscape, which I hope won't cause any problems.

Would there be any interest in adding this to the Breeze set? The licensing is OK with me as far as I can tell.
