When people think of custom apparel, T-shirts and hoodies dominate the mental picture. But for a custom-apparel shop (like what you’re building with iCustom), the “extras” — mugs, banners, flags, signs, accessories — are where margins, differentiation, and brand impact often lie.

This post is your deep dive guide into what else you can customize, how these products differ (in materials, printing technique, turnaround, cost), and how to choose which ones make sense for your business or a client’s project.

Why expand beyond garments?

Before exploring the options, here’s why these extras matter:

Diversification: Garments often have seasonal demand. Products like mugs, banners, flags sell year-round (events, branding, signage).
Higher margins: Some non-garment items carry better markup, especially when customization adds perceived value.
Cross-sell opportunity: Someone ordering shirts might also want matching mugs or event signage.
Branding reach: A mug or banner travels differently than a T-shirt; visibility is different.
Lower inventory risk: Some of these items (especially banners and signage) may have longer shelf life or be made-to-order, reducing waste.

So, exploring the field of customizable “extras” isn’t just a fun side project — it’s strategic.

Categories of customizable extras

Let’s map out core categories of non-apparel customization and what makes each unique.

Product	Common Materials	Customization Methods	Key Constraints / Considerations	Typical Use Cases
Mugs / Drinkware	Ceramic, glass, stainless steel, enamel	Sublimation, UV printing, ceramic decal, laser engraving	Surface shape (curved, cylindrical) complicates wrap printing; high temp resistance; dishwasher durability	Corporate gifts, promotional giveaways, cafes, merchandise for stores
Banners / Signs / Flags	Vinyl, mesh, fabric, canvas, PVC, foam board	Large format digital printing, dye sublimation, solvent / eco-solvent inks, UV curing	Wind load, outdoor weather durability, seam & hemming, grommets, bleed & margin, double-sided printing	Event signage, storefronts, trade show backdrops, outdoor promos
Flags / Flags & Pennants	Polyester, knitted flag fabrics	Sublimation or dye-sublimation, digital printing	Wind stress, hemming, pole pockets, double-sided print with bleed	Parade flags, marketing flags, building flags, community events
Stickers / Decals / Labels	Vinyl, adhesive films, paper with coating	UV print, cut vinyl, screen print, lamination	Adhesion to surfaces (glass, plastic, metal), outdoor durability, die-cut precision	Branding on packaging, car decals, promotional stickers
Sign Boards / Cut-outs	Foam board, corrugated plastic, acrylic, metal	UV flatbed printing, CNC cutting, routing	rigidity, mounting mechanism, thickness, edge finishing	Office signage, directional signs, shop window displays
Other merch	Keychains, pens, coasters, calendars, mousepads, phone cases	UV print, pad print, sublimation, laser engraving	Material compatibility, color fidelity, small-area printing	Promotional giveaways, corporate gifts, event merchandise

Each category brings its own technical quirks and operational demands. Let’s zoom into mugs, banners & flags, and then wrap up with decision frameworks and tips.

Mugs & Drinkware: Turning a sip into brand touchpoint

Why people love custom mugs

Everyone uses mugs. They live on desks, in homes, in cafés.
They are daily visual reminders of the brand.
They make strong gifts and merch items with emotional value.

Technical challenges & tips

Curved surfaces: You’ll often have to wrap artwork or “distort” slightly to match curvature so that design looks correct when curved.
Heat tolerance & firing: With ceramic mugs, if you use ceramic decal or sublimation, the mug must pass through extreme heat (kiln or oven). That limits certain surfaces and adds cost.
Print alignment: Left-hand vs right-hand view (i.e., will the logo face outwards).
Bleed & safe zones: Always leave some margin so print doesn’t get cut or warp across edges.
Durability (dishwasher, microwave): Use inks / techniques that survive cycles. Some cheaper print methods peel or fade.
Color vibrancy on dark mugs: Requires white underbase or base coating.
Volume & MOQ: Some suppliers require bulk orders for custom mugs. (According to 4AllPromos, mugs “are best purchased in bulk to reduce unit cost.”)

Example product

Here’s a sample you might offer / reference in your catalog:
Custom Printed One Of A Kind Coffee Mug — a ceramic mug with full-surface print options.

You can also offer variants: stainless steel travel mugs, enamel camp mugs, or double-wall glass mugs — each with its own constraints (e.g. metal surfaces need different inks/engraving).

Banners & Flags: Big statements, wide reach

These are visual beacons — they communicate far and loud.

Banners / Signs

Materials & styles: vinyl (PVC), mesh (for windy areas), fabric banners, retractable pull-ups, tension fabric backdrops. VistaPrint offers banners in fabric, vinyl, mesh, plus flags.
StaplesPromo lets you customize banners and flags, with options for 24-hour production.

Printing methods: wide-format digital printers (eco-solvent, UV-curable inks), dye-sublimation (for fabric banners), backlit printing for signage.

Design considerations:

Resolution & scale: Large prints require high-resolution designs (300 dpi at full size or vector).
Seams & gussets: Big banners may be made of panels stitched. The seam line must avoid critical parts of the design.
Border / bleed / margin: Always include safe zones to avoid cropping.
Grommets / reinforcement: Edges should be reinforced (canvas binding) and have grommets or pole slots so the banner can be mounted without tearing.
Double-sided printing: For flags or banners where both sides are visible, you’ll need double-sided printing or a bleed-through strategy.
Weather / UV resistance: Use inks / materials that resist sunlight, rain, wind. Mesh banners help with wind, letting air pass through.
Mounting logistics: Know whether the sign will be wall-mounted, staked, hung, or free-standing.

Flags / Pennants

Flags are like banners under wind stress, so the constraints intensify. You need:

Durable stitching (especially on edges)
Pole hems / pockets
Double-sided design or bleed-through print
Wind-tested fabrics (rip-stop, fade-resistant)

Flags amplify brand visibility by moving in wind; people see motion, not just static text.

Turnaround times & trade-offs across product types

One reason garments dominate is that you’ve already built flow, equipment, staff. These extras can bring bottlenecks:

Longer production / curing times: Mugs may need kiln firing / heat cycles. Banners require drying / curing of inks.
Higher setup overhead: Large-format printers take time to calibrate, test, and adjust color profiles.
Logistics & shipping size: Banners and signs are bulky; mugs are breakable; packaging matters.
Proofing and samples: You’ll often need test prints to check colors and alignment, which slows things.
Bulk vs small order trade-off: For banners, making one or two may cost more per unit due to fixed setup.
Rush options: You can designate “fast lane” jobs if capacity allows, but you’ll want to limit to certain sizes/types to avoid chaos.

Some suppliers advertise “24-hour production” for signage. For instance, StaplesPromo lists “24-Hour Production” on their banners & signs page. But that often excludes large custom sizes, large volumes, or complex finishing.

How to pick which extra product to offer (or pitch to a client)

Here’s a decision tree / heuristic you might walk through:

Audience & context
- Will this item be seen regularly (e.g. mug) or episodically (event banner)?
- Is the customer doing an event, a shop branding, or merchandise line?
Design complexity vs surface
- If the artwork is complex / photographic, favor print methods (on mugs, banners).
- If it’s simple logo / text, many methods (even laser engraving) work.
Durability / lifespan needed
- Outdoor use? UV, wind, rain demand tougher materials and prints.
- Indoor use? More flexibility.
Cost / margins vs volume
- A $500 banner order could yield decent margin; a 10-cup mug order may be tight after setup.
- Bulk orders tend to justify heavier setup.
Logistics & risk
- Packaging breakage (mugs)
- Bulky shipping (banners)
- Installation (sign boards)
Turnaround & deadlines
- For tight deadlines, limit to products you have systems to rush reliably.
- Avoid overpromising on extremely custom sizes or finishes.
Cross-sell potential
- Does this extra item pair with existing apparel orders (e.g. client orders T-shirts and would also like mugs)?
