What Threadline is
Threadline is web-based mockup and artwork proofing software for custom apparel, print, and decoration teams. Teams can turn customer artwork into mockups using supplier photography or images from a custom catalog, then assemble proof packages containing products, colorways, views, placements, and artwork references. A conversational assistant searches the catalog and builds matching mockups from a described request, with 500 actions each month. Connected catalogs include SanMar and S&S. Customers can open branded proof links on phones or computers without creating accounts, approve or request changes on each mockup, and leave notes beside a specific view. Teams can export branded PDF proofs and download full-size mockups. Annotation tools, approval workflows, version history, and guest reviewers are included. Mockups and proof packages are unlimited, while the whole team is covered without per-seat pricing. The plan costs $199 a month. A 21-day trial needs no credit card; afterward, the workspace becomes read-only unless the customer subscribes.

Verdict
Threadline centers on apparel and print proofing, combining catalog-based mockups with customer approvals and exportable proofs. The 199.00 USD monthly plan covers the whole team, but assistant actions are capped and access becomes read-only after an unsubscribed trial.
