I've just tatted a little heart, at a glance you can't even see those superduo beads, the same color of the thread:
I'm very slowly tatting my two edgings, but I managed to have 2 corners for the white one and one corner of the hanky.
P.S. I updated the post sbrilluccicante to add the link to the video offered by the "Georgia Seitz Advanced Class" channel. Thank you for watching.
