I wasn't going to bother showing round 5, because it's the same as round 3, just a row of split rings in alternating sizes. After I started on round 6, I changed my mind, because the color interplay between these two rounds is fascinating to me.
As you can see, the split rings of round 5 complete an oval of rings made in round 6; if the rings and split rings are tatted in the same color, it gives the illusion of being all one round.
I'm very happy with the way this is turning out. So far, it's about 3 3/4 inches (9.5 cm) in diameter, with two rounds left to go. Very small indeed for a doily, and a bit large for a motif, but it doesn't matter since it's going to be framed.
To see this doily in a much bolder color selection, head over to Fox's blog. She's tatted up to this point in a variety of pinks and greens, instead of just the two colors, and it looks great! I really hope she'll finish it despite the setback.
