these stitch markers are brilliant, they are just the right size to mark your place in the pattern but as they are so small they do it almost invisibly. So, you don't get that irritating extra bit of yarn going around the stitch marker that you do with other sized markers. The only thing that lost it a star was the fact that they do not really fit 6mm straight needles, I have not tried on circular ones though. Definitely worth buying and at this price I say why not get two?
