For those who love hand made lace.
I have taught myself to do the P pickups and 2 ds across the picots all at once on the needle before pulling the thread through. The top edge looks correct but the area between the picot and the edge does not - if I don't pull the pickup thread tight then the edge looks messy. The only instructions for inverted tatting on the web are for 2 shuttles.
Many thanks! Cheers! Rosemary
