muskaan asked, "Is it perle tatting?" I say no. Perle tatting results in bumps or picots on either side of the core thread. I played with a couple of different ways to create the look of perle tatting in a chain, but that will have to wait for another post. Thank you, muskaan, for the tat-along tutorial on the Ikuta picot effects. It is very easy to follow and understand.
