So a few weeks ago, I got kinda bored, and was remembering when I used to do cross stitch stuff. Which was for a very short time. I did a couple of character sprites (from pokemon, mostly), and I was thinking about doing one of Tails. Then I realized, I can cross stitch onto crochet! And it's like, way bigger, so I can actually see what I'm doing! And I could make a pillow or something!
So that's how this pillow came to be. And yes, I actually call it my Tailsy Pillow. All I did was find the character sprite, write it down on graph paper pixel by pixel (I'm sure there's an easier way, like ascii or something, but I don't know), and then stitch it on to a giant crochet square. As such, I won't be able to give you a pattern. I will tell you the basics though.
Let's say you want a 40x41 pixel square (which is what this one was). You'll actually need 41x41. Since you're actually cross stitching between the stitches, you can't go around the last stitch on the side, so you'll need one extra. Then the rows you can do as normal. You'll be cross stitching in the holes between the stitches, so you should be able to see where to start pretty easily. Although if you want to practice, make the square bigger than your picture, and not exactly the same size. Then if you mess up and get moved over a few pixels, it won't mess it up and go off the square where you can't do it. It's not that hard to get the hang of. And that's pretty much all there is to it!
