Like others, I like to use the deco stitches on binding, quilting, crazy quilts and an occasional special project ...like a place mat or coaster set or potholder...like that.
On my bucket list for next year is making and mailing postcards. That is where I plan to use lots of decorative stitches.
I have a vintage Husky with cams...lots of cams that contain fun deco stitches. Cam A holds the utility stitches and cams B-H are all full of fun things. And they can be combined for even more. I must take advantage of that.
Also, I have used some deco stitches on card stock and watercolor paper with embroidery thread to make greeting cards. Might do more of those.
