To anybody still commenting on this photo who wants a tutorial or wants to buy one:
This person did have a tutorial at one point, but had to remove it due to some issues for the Homestuck kickstarter, considering that I believe this particular design was used in the official kickstarter for Lemonsnout and Pyralspite. [It might've been. I don't remember too well.]. It still can be found somewhere on the internet. In fact, there are MANY different tutorials for scalemates, squiddles, and other plushies that may tickle your Homestuck fancy. You just need to look them up!
And also, they can't sell you a scalemate. There is a specific law for selling copyrighted (Homestuck) stuff as well as plushies, cosplay, etc, etc.
They have an entire sales FAQ document you can find somewhere (Forgot where.) on MSPA. And I believe they could do art trades with you for scalemates, but I'm not sure if the artist is even willing to make these anymore.
You could probably try to either:
1. Make one yourself
2. Maybe find someone else (Because I'm pretty sure this person is sick and tired of getting messages about scalemate prices and stuff.) who's willing to do some sort of trade with you for one. The only legal trade I know of for Homestuck stuff like this, is an art trade. You could try a different kind of trade if you can't draw, but I'm not 100% sure if that's legal. But yeah.
