After reading the comments on the earlier post regarding colours, I decided to be practical and make some samples for comparison.
It started with this one all done in white, but with beads added in. Tatted with size 20 thread, this snowflake measures about 20cm across.
This second one is using the Lizbeth threads that I received from PaulaC. It is a mix of solid and multi-coloured. This is also in size 20. I was working off the ball for this and had to do a SLT for one of the rings in each repeat. I don't really like to use the SLT in this design because it causes a kink in the chain. If you look closely, you should be able to pick out where I did the SLT.
And for the final one, I decided to go totally variegated and use one of my HDTs. I can't remember what and whose thread this is because the tag has fallen off. It feels like a size 40. The finished motif measures about 8.5cm across. Again, here I worked it with shuttle and ball, but this time I loaded the HDT on one of the EZ-bobs. I did not have to use the SLT this time. Instead I use the EZ-bob as a shuttle to make the particular rings that I had used the SLT for before.
I can't really decide which one I like best.
The one in white brought up a centre design that is not so obvious in the other two.
The solid in the 2nd piece draws attention to an outline of each branch of the snowflake.
These two points may not be easily seen in the 3rd version but it is pretty on its own for the lovely shades of the HDT.
In the end, it depends on the tatter to choose the thread but a little imagination and some creative thoughts can produce an impactful tatting.
