Stitch Rulers are the best knitting companion! A Stitch marker and a ruler all rooled into one! Simply bump the ruler up to the bottom of your needle/hook and work until your piece hits the bottom of the ruler for a 2", 4" and 6" measurement.
 
It is best for projects that you are really excited to had done! No need to get a tape measure when you have completed only half a round before measuring again! 
 
Made with light weight wood to not weigh down your work. Also comes with a coiless safty pin to mark a row or (hopefully not) a dropped stitch!
