Jup. I use Avery as well. Just go to your nearest Office shop (in Australia I use Officeworks). And you should find tons of labels you can try.
Just bring a sample lip balm tube with you.
I use adobe illustrator and photo shop. I also go to Onlinelabels.com and buy my labels for my laser printer. there is a learning curve with adobe but I need freedom of design and for printing works vector format is a standard in the industry. If you need help let me know maybe i can lend a design hand. below is one of my labels that worked on. I also create websites etc. I used to be a Network engineer for IBM . I am familiar with Wordpress and CMS systems as well as HTMl Javascript.
