Super simple. Patrons at the $20 tier and above will, along with all the other items they get at the tier you select, get an item that I designed, but Patreon creates and ships (free, worldwide!) every three months. We're kicking things off with the "Until the Skies Fall" mug, then moving onto the NightBlooming organic tote, then an "Until the Skies Fall" shirt, and finally a fully wrapped NightBlooming mug!
Keep in mind that all tiers that qualify for merch ALSO net you the 15% off NightBlooming Evergreen discount, and if you sign up for a year at a time you take 16% off the total cost, which is like getting the discount for three months, free and pay less overall to pick up the new items.
