@Gingham No prob! I might not be the best to ask about actually making bracelets because I'm new to that too. But for this pattern, when I design it there is no way to tell the generator to treat the two sides like two separate bracelets so that is why it displays the strings in between.
You would want to only do columns 1 - 14 for the left otter, and columns 16 - 29 for the right otter.
