Sometimes you may be listing lots of products that might have similar descriptions, categories and tags. You might find it helpful to duplicate a product so you can just make a few changes to the copied product.
Go to Crafties Control Panel
Click on ‘Products’ tab
Hover over the product you would like to copy (or if on mobile, click on the empty space alongside the product)
You will see the option to Duplicate, click this (once)
Your product will be copied
