I find the coolest buttons on eBay and these were a real find. They are truly antique buttons made from glass that I photographed and extracted, then saved in PNG format at 300 dpi. The preview shows you their size in relationship to a 12 x 12 inch paper. Shadows were added for preview purposes only.
While these are commercial use items, you could also use them in your personal scrapbooking (also S4H and S4O friendly).
No credit required for the use of these items, but it's definitely appreciated. Elements can be used as-is in your scrapbooking kits, but need to be modified for use in freebies.
