Start with a small range
Choose a core tee, a layer and a manageable colour palette. Sample the sizes that need the most adjustment. Create a product sheet with garment code, colour, fit measurements, material composition, print position and care instructions.
Cost the saleable run
Include the blank, decoration, setup, packaging, delivery, sample rejects and any selling fees. In a run costing £360 that produces 45 saleable garments, the cost is £8 per saleable garment before any expenses left out of that total.
Verify claims and prepare to reorder
Keep fibre evidence and any certification paperwork linked to the style and purchase. Use measurable descriptions on your product pages. Record the settings your printer approved, then reorder by product code and variant. Test a new batch if fabric or shade has changed.
