ThreadHeads is a custom print studio with its own retail line. You pick a blank, drop in a photo or your own artwork, preview it in their builder, and they print the finished garment and ship it to you. The builder handles background removal, text, and effects, and most custom orders ship within a few business days. There are no minimums in the online builder, and bulk discounts apply automatically from 5 units up.
For bigger jobs there is a managed path: send a brief, get a quote plus a mockup to sign off, then they print and ship. That path starts at 10 units and suits team kits, event tees, and brand runs, with white-label add-ons like relabelling so your own customers never see their branding. If what you need is a box of finished shirts in hand, that is a real strength.
What ThreadHeads does not appear to offer is a storefront: no creator program, reseller dashboard, or fan checkout was found on their public pages. You are the buyer there, paying per garment. Confirm current prices and tiers on their site.
