I'm currently knitting a shawl with well over 400 stitches, and keeping track is driving me mad! These little markers really do help.
I've listed the most 'common' values, but if you'd like others you can create your own using the custom option. Just pop a note in the custom box with the value you'd like.
Each comes on a bulb pin, ideal for moving around your work, or removing them totally. You can also create your own sets with the numbers you use most of.
The markers come in wood, clear and rainbow, but I have other colours available - please send me an email to double check. If you select rainbow, just pop a note of the colour you'd like in the 'custom' box.
