Shop 'Pick Your Print'

🧵 Shopping from our website? Just a heads-up: items on this site are made by our partner in China, while our Etsy products are made in the USA. That means differences in fabric, fit, and price - they’re not exact matches.

🇺🇸 Ordering from the USA? We’ve tested many US orders recently (May/June 2025) and all small parcels arrived quickly with no extra tariffs or fees. However, customs policies can change without warning, and any import taxes are the buyer’s responsibility. We’ll always do our best to make shipping smooth and affordable, but can’t control customs once it leaves our hands.
