One photo is all I have, but that shall hopefully suffice.
Turns out the crocheted slip stitch bind off is fairly integral to this pattern, there being none other I can think of into which it would be equally graceful and snag-free to weave a blocking wire every other stitch. And this is especially tricky through the X section.
If you can't crochet a slip stitch, whilst knitting a Moebius is the time to learn. An ironing board is simply inefficient.
