Hi @gcals ,
This is Theodore from PageFly - Shopify Page Builder App.
You want a theme with “product customization” features. This lets customers add text or notes to products during purchase. Look for themes with “product options” or “customization” in their descriptions on the Shopify Theme Store. These might have it built-in, or work with customization apps like “Product Customizer by E-commerce Tools”.
Best regards,
