Redbubble T-Shirt Design Collection

I run a growing Redbubble shop and want to add a new line of original, print-ready T-shirt graphics. Your task is to create a set of high-quality designs that I can upload straight to the platform without additional tweaking.

Scope
• Produce unique T-shirt artwork that fits Redbubble’s 4500 × 5400 px canvas, 300 dpi, PNG with transparent background.
• Supply the editable source file (Illustrator or layered Photoshop) alongside the final PNG so I can adapt colours or text later.
• Because I didn’t lock in a single style or theme, you have plenty of creative freedom—minimalist, vintage, abstract, or a mix is fine as long as each piece is eye-catching and belongs on a premium shirt.
• All design elements must be original or properly licensed; no stock assets that could trigger takedowns.

Acceptance Criteria
1. Artwork uploads to Redbubble without size or background issues.
2. Colours remain vibrant on both light and dark garments.
3. Files are neatly organised and labelled for quick future edits.
4. Listing must be seo optimized

If you love crafting clever T-shirt graphics and understand the print-on-demand workflow, I’d love to see a couple of portfolio samples that prove it. Let’s make some best-sellers together!
