From the maker:
I always plant a few Sunflowers to enjoy in late summer. The birds enjoy them, too. My illustrated version has a grid center for the seeds and stacked leaves all in a warm yellow palette.
The cards are 4 x 5.25" printed on a high quality cover stock with a white A2 envelope. It's blank inside so you may add your own message.
They are individually packaged in acid free sleeves.
