This is a pattern for basic fingerless gloves. The pattern as written will make gloves to fit an average adult woman’s hands but it can be easily sized up or down.

Less than a skein (100 g/170 yards) of worsted weight yarn is needed for the main color and a little scrap yarn should be enough for the trim.

The full pattern is below. Both gloves are made in the same way.
