I'm not sure if Avery has sets to make circle lables, but I have found a couple of sets in stores that will work for printing the circle designs onto, and then you'd just need to cut them out after printing so the final stickers are circles.

The Avery 18126 (a.k.a. 8126 and 5126) set will make 5.5" x 8.5" labels, 2 labels per sheet. So you could print two 5" circle stickers on each sheet of those.

The Avery 15264 set will make 3.33" x 4" labels, 6 per sheet. So with this set you could print six 3" circle stickers per sheet.

I made some images for the Rush Limbaugh sticker that will work with those two sets.

Here is a PNG image to print 5" stickers, 2 per page, using Avery 18126 address labels: https://i.maga.host/gHCjQSi.png

Here is a PNG image to print 3" stickers, 6 per page, using Avery 15264 address labels: https://i.maga.host/mju5PtY.png

I can make images like this for any (or all :-) of the other circle sticker designs, if you tell me which ones you are interested in, and which Avery set(s) you want to use.
