I too have joined
tatting the Spring Napkin doily by Renulek. It must be a huge tat-along since there are lots of pictures of wip both at Intatters and on Facebook. So I have decided to do mine too, even though from the start I know I will only do some of it because the big doilies are so fiddly to do. And I can see a good place where I can stop, lol.
The thread is Flora size 20 where I use a variegated combined with a white - like I do with most of the doilies I have done in recent years. It just feels good for me to do them this way because I would get a bit bored doing larger doilies in just one colour.
So far no problems, the design is just rings and chains which is the kind I like and do the best.
