I confess to looking and not responding to your post because I have no idea what you're asking. Perhaps others did the same.
Are you wanting to "write" something on the blanket without using embroidery and/or cross stitch? If so, there are fabric paints, crayons, and pens that will work to some degree on a bumpy surface.
Otherwise, yeah, I have not a clue what you're trying to say: what does "including a pick" mean? Why do you need to label the sampler? In short, what the heck are you talking about?
(Somehow I'm thinking this isn't the kind of response you were expecting.)
