Juniper Cafe blade sign installation, starring croissants, ladders, and one very loud little circle.
A bright custom lightbox blade sign for Juniper Cafe in San Francisco, made with laser-cut white plexiglass, translucent UV printed vinyl, and enough sidewalk energy to qualify as an unofficial street performance.

Memorial Day 2025: the croissant line has entered the chat
Lauren at Juniper Cafe needed a blade sign with real presence: bright, round, readable from the sidewalk, and cheerful enough to compete with the smell of laminated pastry. Bam. In your face. Here's the sign. Here's the door. Here's your pastry.
We showed up on Monday, May 26, 2025, which was Memorial Day. Juniper already had serious "Best Croissant in San Francisco" credibility from its 2024 win, and by 2025 the public had clearly received the memo. People were lined up from two blocks away. People like waiting in line in San Francisco, but for this cafe, there's a reason. Somewhere in the sidewalk mix there was street-performer energy, possible busking, definite commentary, and Mikey and Cameron helping me turn a sign install into polite curbside theater.
The job was straightforward on paper: install a custom illuminated blade sign face about 16 feet up. The real-world version included extension ladders, pedestrians, pastry anticipation, camera phones, and in my head, I was thinking, "Damn. There's 75 people here watching me, Cameron, and Mikey. We better not mess this up."

How we made the Juniper lightbox blade sign face
The sign face started as custom-cut sign white plexiglass. We used our Mars 130 laser cutter to cut the plex cleanly, because circles should be circles, not "yeah, it kinda looks like a circle." For a round lightbox blade sign, that clean edge matters. If the face is off, every little problem gets lit up later.
Then we produced the graphics as UV printed translucent vinyl and installed the vinyl onto the plexiglass faces. The key word is translucent. Regular opaque vinyl can look great in daylight and then block too much light at night. Translucent vinyl keeps the color punchy while allowing the lightbox to glow through the artwork. Juniper's palette is bright blue, green, and lavender, so the sign needed to stay lively instead of turning into a gloomy dinner plate after sundown.
The result was a custom lightbox sign face that could read from the sidewalk, photograph well, and still look like it belonged to a cafe with award-winning pastry discipline. We do similar fabrication for acrylic signs, illuminated signage, and storefront projects that need print, cut, and install handled as one job.
The 16-foot install: extension ladders, spotters, and no heroic nonsense
Blade sign installation is one of those jobs where everyone sees the charming finished sign and nobody sees the quiet checklist behind it. Ladder angle. Footing. Spotter position. Tool staging. Public sidewalk awareness. Hardware. Wind. People with croissants trying to drift into the work zone because the pastry tractor beam is strong.
Safety came first. We used extension ladders, kept the ground support active, stayed clipped and controlled where the site called for it, and worked the sign face into the lightbox without turning the sidewalk into a slapstick routine. The slapstick was emotional. The ladder work was boring on purpose.
The funny part is that from the street it probably looked like a tiny festival: bright sign, people in line, possible busker soundtrack, Mikey calling out positions, Cameron doing that intense installer squint, and me trying to look calm while a very expensive circle hovered above a very hungry crowd.
Questions people ask about custom blade signs, answered without making it weird
What is a blade sign?
A blade sign is a sign that projects perpendicular from a building, so pedestrians can see it while walking down the sidewalk. For cafes, bakeries, restaurants, boutiques, salons, and small shops, a blade sign is often more useful than a flat wall sign because it catches side-approach foot traffic.
Why was Juniper's sign face made from white plexiglass?
White plexiglass, often called white acrylic, is a common lightbox face material because it diffuses light and gives the printed graphic a clean backing. For Juniper, it also gave us a precise round substrate that could hold the translucent vinyl artwork and sit cleanly in the blade sign cabinet.
Why use UV printed translucent vinyl instead of just painting it?
UV printed translucent vinyl is excellent for illuminated signs because it gives you detailed color, crisp artwork, and light transmission. Paint can be beautiful, but for a bright graphic lightbox face with exact brand colors and repeatable production, printed translucent vinyl is the practical hero.
Can you make this kind of sign for another cafe?
Yes. If you need a custom blade sign, lightbox sign face, storefront sign, acrylic sign, or illuminated sign in the Bay Area, we can help with fabrication and installation. Start with the sign location, approximate size, whether it lights up, and photos of the building. Our project form is the easiest place to send that.
Do you handle the installation too?
For Bay Area jobs, yes. We fabricate in Berkeley and install throughout San Francisco, Oakland, Berkeley, and nearby service areas. This Juniper project is a good example: custom fabrication, printed graphics, ladder work, and final storefront installation handled by one crew instead of four separate email threads wearing a trench coat.
Need a custom blade sign or illuminated storefront sign?
Bring us the building, the logo, the weird install conditions, and the dream. We will help turn it into a sign people can actually find from the sidewalk.
