I'm so lucky to be involved in an international Irish Crochet project for an upcoming museum exhibit. I can't share all the details but I can let you know that we have people contributing from France, Moscow, England, Northern Ireland, Australia and three states in the US. I can also show you part of my contribution. These little motifs are 2.5 inches wide and tall, and are made with No. 80 DMC Cordonnet Thread and a .6mm hook. TINY stuff to work with! I end up doing a lot by feel and instinct, rather than actual counting of the itty-bitty stitches. The motifs are from the Priscilla Book 1, motif number 36.
