Enable the App Extension in Your Theme

Fabric Lens requires adding an app block to your Shopify theme so the pattern visualizer displays on your product pages. No code required.
  1. In your Shopify admin, go to Online Store > Themes.
  2. Click Customize on your active theme.
  3. Navigate to the product page template in the theme editor.
  4. Click Add block or Add section and search for Fabric Lens. Select and add the app block.
  5. Position the block on the page where you want the pattern visualizer to appear.
  6. Click Save.
You can also enable the extension directly from the Dashboard by clicking Step 1: Enable extension on your store.

​
Verify the Integration

After saving, visit a product page on your store and confirm the Fabric Lens pattern visualizer is visible. If it does not appear, check that:
  • The correct product page template is selected in the theme editor.
  • The product belongs to the collection configured in the Rules page.
  • The Fabric Lens app block is positioned above the fold on the page.
