You can adjust the size accordingly to what you want. All you got to do is to add more increase rounds or subtract some increase rounds. You can even chain as long or short as you want for the strap. I’ve made a simple pattern that’ll work up quick for those who don’t want to spend more than an hour on a project.

Materials:
Worsted weight yarn
4.00mm hook
Scissors
Needles to weave in ends.
