Which input fits your T-shirt design workflow?

The production workflow stays the same. Only the way you provide the design idea changes.

Create one T-shirt design from an idea
Describe the motif and composition first, then add optional exact wording and choose style, garment tone, and variants. This works well for individual artwork and quick new directions.
Create a T-shirt design from a reference image
Add an image you own or have the right to use first. Then choose design mode, garment tone, and variants. MerchKern creates an independent sibling design rather than a copy.
Create T-shirt designs in bulk from CSV
Upload design name, niche, artwork description, wording, style, and color palette row by row. Review the preview, correct individual fields, and start the batch with your chosen garment tones and variants.
