Sometimes you have to cross over an earlier stroke. This is a common problem when digitizing a Celtic knot, which has art that goes over-and-under repeatedly. One trick that is used is to have the Exit point of one stroke align with the Entry point of the column that is going to pick up on the other side. This means an exposed connective stitch will go across the ‘Over’ column, but its angle will be similar to the angle of the satin stitches that it is going across, thus it blends in. As long as the stitch will be short, usually under 3mm, you can avoid adding an object for it. Otherwise, simply add a Manual stitch object with two points, and make sure you go the right direction across.
