I'm looking for a good (inexpensive) site that sells custom stickers.

I would like round stickers with the recycle logo on them, ideally with a custom message, to attach to packages I send out.  Right now I am using teeny, tiny Avery perforated labels that are designed to close folded sheet flyers.  They are a PITA to print myself. 

I've used VistaPrint.com in the past for all kinds of stationery products like Address Labels, but they don't offer round (or even sqaure) labels.

I thought I hit the jackpot with these on eBay but the seller decided they weren't supposed to be for sale and refunded my money.

I just know someone in this forum will be able to point me in the right direction.

this site says they can customize any of the stickers.....

vista print always seem to have some great items (and pretty resonsable and sometimes they even offrer discounts

You could make your own - buy round white labels and download free software from Avery

ETA: I just saw you are printing small ones. I've had really good luck printing on 1.5" rounds. Also, are you using the Avery DesignPro software to print? http://www.avery.com/us/Main?action=software.AverySoftwareDetail&catalogcode=WEB01&softwarecode=3200

I LOVE VistaPrint!  You would not believe the amount of their products I have.  I even got my pseudo-mother-in-law Christmas cards for her to send this year for free.  They don't do shapes other than rounded rectangles, unfortunately.  (BTW, VP sends out email advertising their sales and free products.  You can keep them and use that link to get the deals even after the date the sale ends.)

I have tried Avery Design Pro.  I will have to try it again.  I haven't figured out how to put text that curves above an image as well as below.  I think I am going to just use 1.5" or 2" Avery circular labels.  (I did use Design Pro to make the small ones.)

Also, have you thought of a self-inking stamp instead of a sticker? Just brainstorming...

(I thought I saw where someone had stamped a recycle symbol on the back of a book pkg and then realized it was just clever wrapping with a grocery bag [where the symbol was imprinted])
