Fulfillment!
I'm currently knitting three scarves that are a 'custom' order from my website, Marcia's Makings. That is the point, after all-- to make things that people WANT, especially if they ask for it in certain colors or styles. It's all the same price but, it's a matter of what they think of versus what I think of. I'm more than willing to knit or crochet or embroider or quilt something by request-- it doesn't cost more, so why not?
