Download Gimp which is an open sourced image editor that I put on par with Photoshop.

It just takes some practice to understand how layers work, but it's not rocket surgery.
I just find the TM image of the brand name online and then put that in a mailing label format and type the name of the blend, date, weight, and genre of the tobacco. But, i prefer my labels on the side of the jars. I have over a thousand jars stacked in several cabinets. If I put the label on the lid, I would never be able to find what I want.
But, to do round labels, you could just find the label online, like smokiepiper says above.
