Thank you SO much to all who took the trouble to help me out with this snowflake. I sort of thought I must have seen similar before and didn't think for a minute that BC3 had come up with an original flake. BUT having said that I'm still going to share it.
There is a similar snowflake here which was kindly pointed out to me. The differences are there but I will be putting a link to Betsy's snowflake on the pattern when I've finished it. I think that's fair, don't you? Betsy starts with six rings in the centre of hers whereas mine starts with a mock ring/chain round a central bead. Then I carry on with chains with rings on the chains too. The clovers are also split up with chains too.
Anyway, I'd still value opinions on whether I should go ahead or not. Please leave a comment so I can get the gist of what people think.
By the way - this design started off using this pattern!!!! No, don't ask - I've no idea how I landed up with the Crystal Snowflake!!! Blame BC3 - like I do!!!!
