Make a tee that says NIGHT SHIFT in chrome letters, put it on a black Bella+Canvas 3001, show me mockups, then add it to my Printful store at $29.99.

The tools

Tool What it does Cost
aetherwave_merch_garments Tees, tanks, hoodies and hats: colors, US in-stock sizes, print areas in inches, embroidery thread colors free
aetherwave_merch_prepare_design Turns any image (gallery link, data link or a local file) into a transparent, trimmed print file. knockout removes a plain background without eating white lettering inside the art 1
aetherwave_merch_mockup Builds the print file at the garment's real print area and resolution, then renders Printful mockups. Up to 20 an hour 3, refunded if the render fails
aetherwave_merch_mockup_status Checks a mockup that outlived the 90-second wait free
aetherwave_printful_create_product Creates the product in your own Printful store free
aetherwave_printful_list_products Lists your store's products free

A wrong garment, color or placement is refused before anything is charged.

Connect your Printful store

The two store tools appear only on the npm package (the API key option in Connect AetherWave to Claude), and only when you add your Printful token to the server's settings:

"env": {
  "AETHERWAVE_API_KEY": "aw_live_...",
  "PRINTFUL_API_TOKEN": "your Printful private token"
}

Create the token in Printful under Settings, then API; a private token for one store is simplest. Add PRINTFUL_STORE_ID only if you use an account-level token.

The token is only used between your machine and Printful and is never sent to AetherWave. The Claude connector never asks for it. From Printful, products publish to Shopify, Etsy and your other channels as usual.

Before you sell

Printful charges you per order for the garment, printing and shipping, and often US sales tax. Make sure your price covers it, and only print artwork and words you have the rights to.
