These markers are something I now use in my weaving that I thought you may find useful as well. Numbered length markers!
Keeping track of the length of my work as I was weaving was awkward. I was measuring, placing a marker, and then writing down the length, keeping track on a sheet of paper. If I remembered to write it down... SO, after some thought, I came up with some little round numbered markers. I just measure and clip on the appropriate numbered tag. Before I advance my warp, I measure from the last marker, and clip on the next number. Remove the previous clip, advance my work and keep going. The little discs can also be doubled up, like a 30 and a 4 for 34" etc.
The BASIC set comes with 14 numbered tags and 4 bulb clips.
The ADD-ON set has numbers, in increments of 10, from 50-120
