One of the things I did last week is re-visit this pattern once more.
This was after a discussion with another tatter who very kindly pointed out that it might be helpful to add numbers to the figure 4. Of course this led me to remake the whole thing just to see what else might be needed to improve it!!!
I did a few more tweaks and then uploaded it over the weekend. I still can't fathom how I managed to design this with two very different thicknesses of thread!!! I remember it was quite a challenge at the time but one I'm proud of managing to complete. I must try this idea again - sometime!!!!
