Slowly advancing through the book 'Easy Tatting'...
Here's my first attempt at the Large Heart and the tidier example from the book. I didn't pay enough attention to the sizes of the various picots that I was supposed to make so it is quite wobbly-looking and I definitely need a bit of finesse along those edges and joins.
Here's the center section only of the Large Rosette done in two colors. This doesn't lay flat, probably because the two threads are of slightly different thickness.
