I was amazed with Jane's project of filet crochet and remembered that Mary Konior had a filet pattern in her 'Tatting with Visual Patterns' book. So I had to give it a try. I added an extra row in between the diamonds because I wanted them separated. It is quite slow going for me but I am thrilled with its progress. According to Mary Konior, you can adapt any filet crochet pattern into tatting using this method.
