This should fit the average adult hand as written. Tips for increasing width are included. Also, a quick note on yarn selection… Using DK weight yarn will result in a more snugly fitting arm warmer. If you prefer it to be a bit looser, use worsted weight or increase the width a bit. I have made it in both worsted (Red Heart Super Saver) and in DK (King Cole Riot DK).
