I think postage stamps are pretty cool. I am not a collector by any means. Before I went on my self imposed moratorium on buying craft supplies, I bought a few stamp lots on Etsy. One included several beautiful butterfly stamps. So I made some cards with them (I know that is a big surprise for those that know me).
At least ten years ago I went to a scrapbooking convention in Mesa, Arizona. There was a booth with a great deal on paper. A bought about twenty packs of 8.5″ by 5.5″ paper. Perfect for quick cards. So, in line with my theme for the year of using what I have, I didn’t buy anything for these cards. Yay me!
