We've heavily researched the most common material and size variations available online, and have made these options available to you for your Store. However, we recognize that a "one size fits all" may not always work, and as such, material variations can be added to existing Online Design Products. If there is a material option not listed here, you can request that we add it to your Online Design store (not all requests can be granted).
To request that a material or size variation be added to your Store, please submit a support ticket outlining your request.
To add this yourself, please view this article - Add your own variation options for Online Design Products.
