I am sorry Gillian, what I meant by 'basic' is some simple patterns where the interlacing aren't that many. But I looked through the free Celtic tatting pattern instructions from your link at BellaOnine, and if I understand it correctly, it is a design style made up of several tatted pieces assembled together in a creative way.
I decided to try the bookmark by LaRae Mikulecky. Sections One to Three were easy enough, but I got stuck when starting Section Four. I am not sure how to start. Do I join the thread to the first picot before starting the first chain or do I join it at the end? And, how do I make this join?
I usually tidy up the thread ends by the magic thread method, one at the beginning and one at the end of the round. For this round, it would be easy enough if I start with CTM. But if I still have some more thread in the shuttle and do not want to wind a new shuttle, I will have four thread ends to hide. Where would be the suitable place to put in the magic threads?
I hope this isn't too much for you at one go.
