Without twists in the doubled line, feed it into the snap swivel eye.
Take the loop over the top and pull tight, keeping the center mark in the middle. You might need tweezers to get the loop to the bottom of the swivel eye.
Continue with the next doubled line being aware of how the line sits in the swivel eye.
Try to keep the next tied line beside or on the other side of the previous looped line. Just watch for line overlaps and twists.
Like any other technique, it'll take practice. In the end it should look like the first picture in the last post.
