I can create a sprite at the maximum size of 32x32 pixels. If the sprite you're looking for is slightly larger than these dimensions, give me a shout and we can talk about it. Larger sprites take much more, are more difficult to ship and generally is a more expensive process.
If you want, I can apply a magnet to the back of the sprite. These make great refrigerator decorations! Given that these beads have holes in going through them, you can also string up these sprites to hang.
