2 m of silicone stitch holder cord. Attach to the end of your knitting needle and slide the stitches on to the cord. Can be cut to size for different projects. Great for placing stitches on to measure garment size as you knit. 

2mm cord hole is 1mm diameter but stretchy and I have used on needles up to 4mm. 

4mm cord has a 2mm hole and will fit larger needles.

It will depend on how pointy your needle tips are!
