So, the longer that I knit, the more needles I accumulate. I'm afraid that eventually I will misplace the packaging and not know what size the needles are. I have a gauge now but it doesn't take into consideration all of the different sizes in millimeters, e.g. the two sizes for US 1 and the two sizes for US 2. I've looked online but I can't seem to find one that has these sizes. Can anyone point me in the right direction?
