You can use any worsted weight yarn but I find Caron Simply soft tends to be a bit more flexible.

You will need 2 skeins of yarn (one in each color) but you will have plenty left over.

To alter the size of the glove simply use a bigger or smaller hook.

Update

There seemed to be a bit of confusion with the wording in the pattern so I’ve made a few changes and now hopefully it’s easier to understand!
