I like to play as you know and this is the set I made with a different doodad for the centre.
I wanted to prove to myself that it doesn't matter where you join as long as you have eight places in a doodad and that it measures 1.5 centimetres (or thereabouts). By thereabouts a millimetre more or less shouldn't make a big difference and the doodads I've got all seem to be roughly 1.5 in places anyway.
Can you see the necklace 'thingie' (can never think of the right word for them) below? Joanie sent me home from her house with lots of them and I really, really love them as they're adjustable and easy to put on and take off. I use a metal split ring at the top of the pendants so that I can slip the tatting on and off just the one necklace as and when I change to another colour. Well, that's in theory!!!!
