You can make these creepy Halloween Eyeball decorations in three different sizes
They are knitted around ball pool balls and ping pong balls.

Small – 12.5 mm (ping pong/table tennis ball)
Medium – 17 mm (small ball pool ball, mine were from Poundland in net bags of 15.
Large – 20 mm (regular size ball pool ball which I have found in supermarkets and charity shops.)
They are a great way to recycle old plastic balls.

The yardage includes all the yarn. The smallest eyeball takes approximately 4 grams (15 yards) Medium 6 grams (22 yards) and the large 8 grams (30 yards)

The metallic yarn is knitted double apart from the red.

Skills required are cast on, cast off, knit purl, Increase (by knitting in front and back of stitch) decrease by knitting/purling two together)
and stripes (tying on a new colour and cutting the last one)

They are very quick and easy to make and my boyfriend has ordered several to decorate his 57 Chevy.
