I could not afford similar marker but really wanted to have some so ai decided to make my own in various sizes to accommodate knitting on both bulky yards and lesser weight yarn. I tried using some other removable stitch marker like the circular plastic one but it would fall off the work. It create near misses to where I could have lost track of my rounds, rows, or stitches.
These are the result. I will continue to make more of them to have sets for when multiple stitch marking is required.
