Let's take a look at how the items property works for our tokens:

weight: {
items: {
light: '300',
property: 'font-weight',
variable: true,

The items value tells Blyth what tokens to create for our token. In the example above, we're creating a light font-weight with a value of 300. The light part is the design token name, whilst the 300 is the value of the property you're looking to use.
