I’m not a spring chicken anymore and more and more I’ve been noticing that I am blind as a bat. I was trying to find the correct crochet hooks for a project and the larger hooks I have are these clear colored plastic hooks with the size etched into the end of the handle. I’m sure you know the ones. They are Susan Bates Crystalites. Susan bates also has the hooks that are all white which have the same issue. When I was looking for the larger sizes like L (8 mm) and N (10 mm) these were all I could find here locally. With no contrast it is very difficult to read the size. I finally got a bright idea and I dabbed some white acrylic paint over the size on the handle and tapped the paint around with my fingers to fill in the etched in area. Then I wiped off the excess with a paper towel and now I can see it perfectly! If you have the white ones you could use any bright color or black. The same thing applies to the knitting needles of course.
