Are you familiar with PixelHobby? To quote their website:
PixelHobby is a new mini-mosaic craft. (…) PixelHobby designs are based upon small plastic tiles called Pixels. Pixels are available in over 300 beautiful colors. The molding process creates a soft plastic tile with a matte finish. (…) Each pixel location on a baseplate provides a small peg onto which a pixel is positioned. No adhesive is necessary to hold a pixel onto a baseplate since a snug fit occurs between the pixel and baseplate peg.
You can show your passion on 4×5 inch baseplates, but also use medaillon-sized plates. I’ve already spotted PixelHobby in my local crafts store, and in various online shops, including their own.
The PixelHobby website offers various designs. If you want something unique, get the PixelHobby Designer Lite and make your own pattern based on photos, art and other images. Or, recreate a sprite! One of my favorite websites for this purpose is Spriters Resource. And finally, nothing keeps you from going with the flow. Don’t use a design or pattern if you don’t feel like it.
Here’s a small preview of what you can do with the craft. Wacker00 is a real genious when it comes to PixelHobby and perler beading and you should definitely visit his DeviantArt!
