This is a written and charted pattern for fingerless mittens or gloves.
Measure your handsize: Wrist circumference and hand circumference if the mittens will fit your hands. The hand circumference is measured at the widest part of your hands - your palms.
You could adjust the pattern to fit your hand size.
Since my teens I have been working with textiles and fibers .
As a hobby I design crochet patterns.
