I have both Embird and 5D and you can make your own decorative stitches in either of them and it's quite simple. You can then use them as you would any of the built-in stitches. I guess you can do the same in most digitising programs.
I wrote a mini-tutorial some time ago on how to do it in Embird.
I think it is quite likely that she has made them her self. Have not seen these before!
