Why the Edges Matter More Than You Think

When a Brighton business orders a banner, most of the attention goes on the artwork — the colours, the font, the logo placement. That is understandable. But the part that decides whether your banner still looks smart after a gusty weekend on Madeira Drive is the finishing along the edges. A printed banner is only as strong as its weakest point, and that point is almost always where the eyelets meet the fabric.

Get the finishing right and a banner will sit taut, flat and professional for years. Get it wrong and you will be watching the corner flap itself to shreds before the summer season is out. Here is what you need to know before you specify your next order.

What a Hem Actually Does

A hem is a folded and welded strip of the same banner material running along each edge. It is not decoration. It adds a double thickness of material at the point where stress concentrates, which is exactly where ropes, ties and bungees pull.

There are three common approaches:

• No hem, cut edge only. Cheapest option. Fine for an indoor display that will be taped flat to a wall and never pulled. Not suitable for anything that will be tensioned.
• Standard folded hem. The edge is turned over by around 25–40mm and heat-welded. This is the sensible default for most outdoor and event work around Brighton and Hove.
• Reinforced hem with webbing. A strip of polyester webbing is welded into the hem itself, or run along it. This is the belt-and-braces option for large banners, exposed coastal sites or anything that will be re-used season after season.

If your banner is going on a seafront railing, a pier approach or an exposed corner site in Kemptown, the webbing-reinforced hem is worth the small extra cost. Wind loading on the coast is not a myth, and a banner that flogs itself against a metal railing will fail at the hem long before the print fades.

Brass Eyelets, Stainless Steel and the Alternatives

Eyelets are the metal rings set into the hem at regular intervals. They take the fixing, whether that is a cable tie, a bungee, a rope or a hook. The two things that matter are the material and the spacing.

Brass eyelets are the traditional choice. They resist corrosion well, hold their shape and look smart. For most applications they are perfectly adequate and are what you will get as standard from a decent printer.

Stainless steel eyelets cost a little more but are the better choice for genuine long-term outdoor exposure, particularly within a few hundred metres of the sea. Salt air will eventually dull brass; stainless steel shrugs it off.

Plastic or painted eyelets exist for lightweight indoor use. They are fine for a pop-up stand used inside a conference venue, but do not put them on anything that lives outside.

Spacing matters just as much as material. Typical spacing runs at roughly 500mm intervals, but for a large banner in an exposed spot, ask for tighter spacing — 300mm to 400mm — along the top and bottom edges. Closer eyelets spread the load and stop the hem from scalloping between fixings when the wind gets up.

Rope Finishes and Pole Pockets

Not every banner is fixed with eyelets at all, and it is worth knowing the alternatives before you default to them.

• Rope sewn into the hem. A continuous rope runs through the hem and is knotted at the corners. This is ideal for banners tied to railings, posts or scaffolding because the load is distributed along the whole edge rather than concentrated at individual eyelets. It also gives you flexibility in where you tie off.
• Pole pockets. A sleeve sewn at the top and bottom lets you slide the banner over a pole or frame. Common for backdrops, marquee signage and stage sets. No eyelets, no rope, no flapping.
• Keder edging. A rigid beading welded into the edge that slots into a channel on a frame. Very common on exhibition stands and tensioned fabric systems. It gives a perfectly flat, drum-tight finish.
• Hook-and-loop or zip edges. Useful when you want to join two banners together or attach one to a fabric wall.

For event displays in Brighton — think festival stages, market stalls on the Level, or a sponsor banner behind a summer concert — pole pockets or keder edging will almost always give a cleaner result than eyelets alone.

Matching the Finish to the Job

Here is a simple way to choose, based on where the banner is going.

• Indoor, short-term, flat against a wall: cut edge, light eyelets, done.
• Indoor, stretched or hung: standard hem, brass eyelets at 500mm, or pole pockets.
• Outdoor, sheltered garden or courtyard: folded hem, brass eyelets at 500mm.
• Outdoor, exposed, seafront or high wind: webbing-reinforced hem, stainless steel eyelets at 300–400mm, or rope through the hem.
• Re-used event display, tensioned frame: keder edging or pole pockets.

One last practical note: allow a little extra in the artwork for the hem. A 40mm hem on each side effectively reduces your visible print area by 80mm across the width and height, and eyelets need clear space inside the hem, not underneath your key text. Tell your printer where the banner is going and how it will be fixed, and they should be able to advise on the right combination without you needing to become an expert in fabric welding.

It is a small part of the order and a large part of how the finished thing performs. Worth five minutes of thought before you press go.
