This is a one size pattern. Despite being designed for an adult head the same pattern could be used for younger people but with a different style that would be closer to a pixie hood rather than a bonnet. I’ve included pictures of it modelled on different head sizes to give you an idea of how it would look.

The bonnet it worked using a worsted weight yarn at a slightly tighter gauge than normal as this provides a more stable fabric on which to embroider.

In addition to the main yarn you will need scrap amounts of a DK yarn in a variety of colours to work the embroidery. The pattern includes a photo tutorial for how to work the embroidery stitches.
