Tried to post again on your site, but cannot post twice on same message.
Anyway, In Scrapper's Alley catalog, 2006 on page 81 they have a selection of stickers and blank bottle caps. Hope this is what you are looking for.
Thanks again Mariend. I have learned that if you want to put another msg in a post, you have to rename the "Subject of Posting" line and then it will take.
I'm off to check the sites you advised me of. I found some bottle caps at an antique store and wanted to make some Halloween decoration for my Halloween tree (same as an Easter Egg Tree if you know what I'm talking about).
