Well, isn’t this interesting….
I’ve taken a look into this. The markings are there and are visible on the 5-12 size. And on the 6M-4 size, the two “x” markings for the button placement are there–they really are. It’s just that they fall right behind the “1A” symbols for joining pages 15 and 16 of the PDF. As a result they get lost in the black of the 1A circles.
If you look at the large pattern sheet on page 26 of the 6M-4 size you will see where they are relative to the other landmarks on that piece. If you’re working with the tiled pattern pieces in the 6M-4 size, you can use the 1A symbols for your button placement.
I’ve updated the PDF file to allow the marks to be seen more easily going forward. If this is a real issue for you and you have purchased a copy of this pattern from us and would like an updated version, please email information@oliverands.com with your request and we’ll make sure you get a new one.
