I have found blogging an excellent stimulus for learning and improving my work. Recently I bought Jon's book of snowflake patterns, and it has been a good way to learn and practise split rings and two shuttle work. These three are my first attempts.
I am also doing a back to basics doily, shuttle and ball, size 50 DMC cordonnet, from the french tatting book. I have only done two rows so far, and there are five, I wonder if I will ever complete it.
