The answer depends on whether you want to order a sample set or create and list a custom-designed product.
Sample sets
When ordering a sample set, you upload your logo and Selfnamed automatically generates the design for you. Because of this, the logo size and positioning cannot be manually adjusted.
Sample sets are intended for testing purposes only — they are not designed to be sold to your customers as a finished product. If your logo appears small or the design doesn't look exactly how you'd like, that's expected at this stage.
Custom-designed products
If you want full control over your logo size, positioning, and overall design, you can do this by creating your design in the Selfnamed Design Studio.
This lets you adjust every detail of your packaging exactly to your liking before ordering or listing to customers.
To edit an existing custom design:
Go to your Selfnamed profile → My stores → open your store
Go to My products and find the product you'd like to edit
Click Edit and make your adjustments in the Design Studio
