No, I didn't knot between them. I have some larger better quality pearls I'm going to try and knot. The lady I buy my pearls from is going to show me how to do it next time I go in to her shop. I have a feeling it looks easier than it is.
Not really! Once you get the hang of it, it's easy. The big thing is having the right tools. If you have decent stringing material, and all the things needed to finish your strand, it's not too hard to do. I have found that the thread you choose makes the most difference.
Once you start with pearl stringing it gets addictive. I've restrung all mine, lots of my friends strands, and new pearls that I bought from Pearllunar.
Good luck.
