PiB means Pearl in Balance. It is a new pattern from Hanny Waldburger. The pearl or zengem as it is in my version is a treasure, that should be protected, not to be thrown to the swines. Read more about that in Hannys blog! I wrote about it in yesterday post and there you find the link to the stepout and what she wrote about it. This tile of mine is my entry to IAST 165.
The other patterns are Verve (JJ La Barbera) and Flux. I couldn´t resist involving Tipple too! I do that quite often as you might have noticed. It comes automatically!
