These textured armwarmers are stretchy and will fit a variety of arm sizes. To size up or down, the stitch count will need to be changed in multiples of 5. The length is easy to customize by working more or fewer rounds. Instructions for optional thumb holes are provided, which converts them into handwarmers/long fingerless mitts.

Sizes - Extra-small, small, (medium, large), extra-large - measurements given below are UNstretched

The ribbed pattern is very stretchy. If you are making fingerless mitts, I suggest that you choose a size with 1/2 to 1” negative ease for a snug fit. If you are making arm-warmers, I suggest no ease or up to 1” positive ease. One of my testers made a legwarmer variation as well!
