A merch range feels stronger when the products belong together without looking identical. Start with the audience and the idea, then choose the garments and graphics that help the range make sense.
Decide whether the collection is for a launch, an event, regular retail, staff use or a seasonal release. That decision affects the product mix and the level of artwork development required.
Set a small group of colours, type styles, graphic treatments and placements. A visual system lets several products feel connected while giving each piece its own job.
Start with the garments that matter most. A tee, hoodie, cap or tote can create a useful range, but only if the products fit the audience and the budget.
Some graphics need a large back version, a compact chest mark and a simplified social image. Prepare the artwork around real placements instead of forcing one design everywhere.
Trap Door Print can help with the visual route through Range / Collection Design, then move the approved garments and artwork into a print brief.
