This is my Retro Space Invaders Beanie Hat knitting pattern. Are you really old enough to remember this seventies arcade game??? The knitting pattern provides full written instructions for 3 sizes S (child), M (teen / woman) & L (man) and there is a colour chart for the colour work part of the pattern. It can be made in any dk (8ply) yarn of your choice on 4 mm needles so is ideal for using up small leftovers. Bring out your retro side and make one of these today. This knitting pattern is available to buy here as an immediate pdf download.
