or a case of gapsosis,
that snippet of thread the peeks out between rings or chains when you do the next element of the pattern, like these examples.
This is the method that I have been using to cure myself of the gapsosis.
I fold the previous element over before tatting the next part.
I don't rush when making the first double stitch of the next element. When making the first half-stitch, I slide the flipped stitch slowly to the beginning, making sure that it is really close to the previous part. Then I pinch this first half-stitch and make the second half stitch, again sliding it carefully to meet the first half-stitch.
Once the first double-stitch is secured, I then go ahead and make the other double stitches at my normal pace. An example of a cured gapsosis is seen at the base of this trefoil where the two chains meet.
Look Ma .... no gaps!
