Step 2 : Add the wire

I used 2mm diameter tie wire that I had sitting about, then starting in the centre wound the wire over the screws in the following order
Start at 1, over 2, around 3, back over the top of 2 then around 4.
From 4 back over 2 to 5, then to 6, over 5 to 7, back over 5 to 8 then all the way back down to 1 and continue to the next arm of the snowflake.
