Hi everyone,
I was wondering how this feature works? When I check the box, nothing happens
Thanks
Ok…you were wondering about the labels… Lesson #1: 
The pattern piece properties:
Is data that is associated with place holders used in the label templates, which you can add by clicking “Insert”:
When you check On Fold it enables the Word on Fold* as a place holder.
Unchecked:
Checked:
In other words, the properties are simply for adding piece data to a label. They currently perform no function. Hopefully they will have a use when I implement the marker feature. The idea is you use one Pattern piece label template, and then check if a piece is on the fold.
BTW… this is an example of the Font resizing that drives me nuts. Just adding the “on fold” changed the font size. 
Now…you’re probably wondering why the Word on fold placeholder? Since the “Word” place holders are hardcoded, they are translatable:
Where if you just typed in “On Fold” in the label template:
They are not translatable.
Let me know when you’re ready for lesson #2.
As you can see that took me a minute to process 
I’m ready for lesson 2 haha!!
I may be a lot less active on the forum over the coming weeks as I’m starting a new project which is more sewing than drafting intensive and will be very busy with that, but still will be dabbling with seamly in the evenings hopefully
