Adorable Ideas, and the one I actually ended up using was a free one that I got when I attended one of their seminars, so I'm not sure if it's available on the website.
I stitched on a couple of napkins that belonged to my late mother-in-law. I don't believe she ever used these -- they didn't feel like they had ever been washed.
They stitched up fairly quickly. The pattern stitches a guideline first, then you have to cut away everything from the guideline. That probably took the longest, because you can't remove the napkin from the hoop. I like the way they turned out, and intend to stitch up the rest of the set.
