Thanks Al Kolka, I think your Torus is splendid also. But I am awestruck by Christine's post because if you trace the line around it appears to be one continuous line (yes, I know it is an illusion but it is not the appearance of three separate rings intertwined). Also, the regularity of the loop pattern is amazing. I have to say I am really knocked out by this quite apart from the logistics of cutting out the shapes and sorting out what goes on top of which. Anyway I haven't got too much work done this afternoon because I have been trying to figure out how it was done and my efforts up to now have been feeble. Please, Please Christine - what's the secret ;-)
