You may recognize the cardigan in the photo -- it's the cover of the Louisa Harding "Gathering Roses" design collection book. It's the kind of thing I like to wear, but I wasn't that interested in knitting it. Luckily, my LYS sold off a bunch of samples, and I was able to snap this up at a very good price.
That was a while ago, and I really never ended up wearing it much. My mom loves this shade of blue, though, so I offered to give it to her. She likes it except for the embellishment, so I'm going to take that off. If this were duplicate stitch, the process would be a pain in the butt -- but it's not. It's just crocheted on.
See? All I have to do is flip to the wrong side of the work, snip the embellishment yarn, and tug. Unfortunately it is a little snaggy and there are some knots, so this will require a little delicacy -- but it won't take that long, and then the cardigan will be able to go to a new home!
I think the embellishment on this project is unecessary -- it makes a nice simple garment too girly for my tastes -- but I do like this style of embellishment. It's a lot quicker and easier to do than duplicate stitch, and it can be very free-form. You can just make it up as you go.
Maybe everyone has tried this technique already -- but if you're interested, I wouldn't mind doing a tutorial. If you haven't tried it, it's a lot of fun. And how about a duplicate stitch tutorial, for good measure?
