sssssssssssssssss BOOM!
At the moment I am completely obsessed with Minecraft and I was inspired by the unhappy looking exploding mob to make this simple iPod cover (i don't do complex things ;) )
Pattern:
Cast on 30 stitches on 4-6mm needles (again it depends on the wool) and knit in pearl and plain until it is the size required to fit whatever version of iPod it is for.
For the face detail use a black/dark grey wool and either cross stitch or long stitch the details on. sew up the sided and the bottom and you have a friendly creeper pal to protect your iPod.
