I create hand-made creams, lotions and soaps and I use these labels on the products I sell in my Etsy shop. I love them because they are so versatile. I can use them on my 4 oz jars and my 6 oz jars. My logo, ingredients and directions easily fit on the label and it looks professional. I was so pleased once I found these labels, I don't plan to use anything else.
I use the label template to design my labels. It took a bit of time for me to figure out the right size and lettering but keep at it until to find the right fit. Stay within the margin and you should be fine.
