Based in South Australia, Oh Hello Sign Co. brings modern, customisable signage to all kinds of celebrations. We mix style with simplicity, offering vinyl lettering and hire boards designed to make your event feel personal and polished — without the hassle.

Oh Hello Sign Co. started with a cricut, a vinyl collection, and a deep love of making things look just right. After four years owning and operating an award-winning party and play venue, our founder Caity knew one thing for sure: people want their events to feel special — but without the stress (or the craft supplies explosion on the dining table).

Now based in the south of Adelaide, Caity brings that same eye for detail and party know-how to Oh Hello Sign Co. From luxe hire boards to custom vinyl lettering, we make it easy to create something memorable — even if you're planning on your lunch break.

We're here for the low-effort, high-impact moments. The signs that pop. The vibe that sticks. The kind of party that people talk about for all the right reasons.
