Patch on knitting?

Has anybody ever put a decorative patch on their knitting? I was thinking about putting a little character patch on my nephew’s sweater when it’s done to dress it up a little, but I didn’t know how it would wear (the fabric is garter stitch and the patch would be stiff).

You can “pre-soften” the patch using a couple of different techniques. There is a series of articles at called frankenknits where you might be able to get some ideas. Otherwise, I don’t think it would be too big a deal. The secret is to sew it down so the fabric isn’t pulled too tight under the patch or to loose!
