Start from a blank canvas or one of the built-in templates — whichever is closer to what you need speeds things up. Set your label size first, since resizing after you’ve added elements can throw off your layout.
From there, add your elements: text, images, barcodes, and fields linked to your product data. Nothing is sent to a printer until you choose to print, so there’s no risk in experimenting with the design.
Once you’re happy with it, save the label. It’s stored in the cloud with your other designs, ready to link to your data and print whenever you need it — see Add text, picture or barcode and the four-step walkthrough for the next steps.
