There are definitely some Great Impressions Stamp of the Month (SOTM) stamps that I find more versatile than others...April's SOTM stamps were so great! If you missed out picking them up from your local store the SOTM stamps for April 2012 (and older) are available from the Great Impressions Online Store!
It would be hard to pick a favorite, but I can tell you that you need to get the Rose Trio and Butterfly Frame stamps!
Aren't those mini banners adorable? Tiny details, colors and glitter...stop by Great Impressions Stamps blog to see more inspiration!
