NOTES
The stuff we wish someone had explained to us.
Years of buying these products as a seller taught us where merch orders actually go wrong. This is that knowledge, written down: supplier decisions, artwork prep, quantities and reorders — organized by the decision you're facing, not by keyword.
Every page states its evidence: first-hand experience, direct observation, or external research with sources.
Choosing & testing suppliers
The questions worth asking before you commit a single order — and how to test a new supplier without moving your whole line.
Comparison How to compare two custom merch suppliers using the same artwork A practical framework for comparing custom merch suppliers on equal terms: freeze the design, normalize the quote, and score ten dimensions that actually predict how the order will go. Buyer Guide How to test a new supplier without moving your whole merch line The one-SKU test: how to try a new custom merch supplier with a single design and a small run, keep the comparison fair, and know exactly what to look at when both samples arrive. Buyer Guide What to send a supplier to get an accurate merch quote The exact brief that gets a real quote instead of a placeholder number: product, spec, quantity curve, design count, destination and deadline — and why each field changes your price. Buyer Guide When should you test a second merch supplier? Six situations where finding a backup supplier stops being disloyalty and becomes basic risk management — from a founder who spent years buying these products before making them. Field Note Why I kept looking for suppliers even after I already had a good one A buying habit that looked like disloyalty and turned out to be the most useful thing I did as a seller — and the logic behind it that now shapes how OFFPRESS treats enquiries.
Quantities, MOQ & first orders
How much to order when you have ten designs and one budget — and what MOQ actually changes.
Buyer Guide How to approve a custom merch sample — and what a sample can't prove The sample is the gate before production: set your acceptance criteria before it arrives, check against them in the right order, use-test the piece where it will live — and know exactly which questions a sample of one does not answer. Buyer Guide Planning a first production run without overcommitting How to size a first merch run you can walk away from: minimum sellable batches, checkpoints between runs, and the reorder trigger that replaces guesswork. Buyer Guide MOQ vs unit price: what actually changes when you order more Why unit price falls with quantity, which costs are real and which are padding, and how to decide the total commitment you can actually sell through — without a spreadsheet full of guesses. Buyer Guide One design across several products, or different designs for each? When a merch line reuses one artwork: what survives the format change, what has to be adapted, and how to choose between reuse, tuned variants and per-format redesigns — before the quantity split. Comparison One supplier or several for a growing merch business? The honest trade-offs of single-sourcing versus splitting orders across suppliers — cost, consistency, risk, capacity and management overhead, without the absolute advice. Buyer Guide How to plan quantities when you order several designs at once Why ordering every design in equal quantities sounds fair and works badly — a framework for splitting a merch order across designs based on how they'll actually sell. Field Note What changed in my supplier search when order quantities grew Small orders and large orders are different sports. What I stopped caring about, what started mattering, and why growing sellers re-quote everything — from a founder who bought these products at every size.
Reorders & supplier risk
The stage nobody writes about: restocking a design that worked, and keeping a second option warm.
Preparing artwork
Files, colour and cut lines — the general principles, kept separate from any one factory's spec sheet.
Product Guide Acrylic keychain options, decided on real pieces Clear vs effect bases, flat vs epoxy dome, single vs double layer, attachments and size — what each choice actually does to the finished keychain, with photos of real pieces. Product Guide Custom badges: size first, artwork second How pin-back badges are made, what the standard sizes actually are, which back type fits which use — and why the size decision comes before the artwork, not after. Artwork Guide Check your artwork at actual size — the 5-minute test before you order A concrete five-minute test that catches the failures that look fine on screen and vanish in production: print at 100%, hold at use distance, check text floors, line weight and silhouette — and know what this test can't settle. Artwork Guide Cut lines, bleed and safe area: the three margins of die-cut merch What cut lines, bleed and safe area actually do, how conventions differ between printers (they really do), and the one thing that matters more than any line width. Product Guide Fridge magnets: strength, construction and the spec nobody asks about Flexible rubber vs rigid magnets, what holding force actually depends on, and why 'what will it hold?' is the one question that prevents the most common magnet disappointment. Artwork Guide Preparing artwork for custom merch: send what you have, or get precise Two honest paths from artwork to production: send a rough file and get help with what won't print, or take control of vector files, resolution, cut lines and colour yourself — and how to know which path you're on. Artwork Guide RGB vs CMYK: why your print won't match your screen — and what actually helps The physics behind screen-to-print colour shift, which colours suffer most, and the only reliable way to settle colour before production: a physical sample. Product Guide Custom sticker options: the four choices that decide the result Die-cut vs kiss-cut, vinyl vs paper, clear vs white base, matte vs gloss — what each sticker option is actually for, and where buyers over-order. Product Guide Custom sticky notes: print areas, sheet counts and pad construction Cover vs edge vs full-sheet printing, why the adhesive is a strip and not a coating, and how sheet count quietly dominates the unit price of a custom sticky note order. Artwork Guide Vector vs raster artwork for custom merch: what actually matters Why vector files scale and pixel files don't, when a PNG is genuinely fine, and how to check whether your artwork will survive production size — in plain terms. Artwork Guide White ink and printing on clear acrylic: why transparent bases need a hidden layer Why colours printed directly on clear acrylic look washed out, what a white ink underbase does, and when leaving the base transparent is the better design decision.
Product decisions
Finish, thickness, material and size — decided on real pieces, not marketing glossaries.

Product Guide Which custom merch format fits your artwork? Match the traits of your artwork — fine detail, silhouette, transparency, text load, how it's used and displayed — to the physical format that will carry them: acrylic keychains, stickers, fridge magnets, badges or sticky notes.
