That's a tricky one. Are you already making amigurumi to sell? The way I see it is, people who can't crochet will be more likely to by the finished product, while people who can crochet will be more likely to buy the pattern. As a crocheter myself, I would never buy someone else's plush because I love the satisfaction of making it myself.I usually end up taking the risk and selling both the plush and the pattern (though I sell more patterns than plushes because I tend to underprice my plushes and tire myself out).Or you can just keep it yourself as a trophy of being awesome.
