This is something I need to find, a good program to design labels (not standard clip
art in their design set), then download as pdf then off to Staples. Based on a lot of comments, printing at Staples seems to be the most cost effective. Printing at home has its advantages and when my ink swilling inkjet dies, a decent laser printer and labels will likely be my long term solution.
I’ve tried Avery, and while its cloud based app is decent, I need to spend more time with it. Canva I’m not familiar with and will do a search.
I use the desktop version of Avery Design & Print, which is no longer available. It's not the most full featured product, but it does what it's designed for, and when I design a label, it scales it across the page, e.g., I get 6 properly placed labels. I print to PDF and print on a color laser printer.
Paint.net is great for modifying graphics, although the learning curve is steep. When I need to do something new, I look for a tutorial. But the tool is not good for labels, as text becomes an object, so it can't be changed; it must be recreated.
I've tried other tools for labels, and while most work fine for design, they don't scale across the page well. I'll check Canva.
For really good labels, inkjets don't work. Media also matters -- I started using Avery Surface Safe White Film for Signs. It doesn't run when printed on a laser, and the labels peel right off. If you misplace a label, you can peel it off and restick with no problem. And when the bottle is empty, prepping for the next batch is simple.
