This is a darling seedling favor diy project that was featured on Etsy's How-Tuesday series. While it's marketed as a wedding favor, I think it could translate well into other occasions. Perhaps a more substantial version would make a sweet hostess or house warming gift, too?!
****My two cents: You could also use a cookie tin to store everything in & use as the container for the plant. One of my carpet companies actually handed out our very own organic wheat grass seedlings kits that way. This was a promotional gimmick from them, but a neat one. Durkan ordered the grass tins in bulk from a company like 4imprint.
To build on that idea, wouldn't this turn into a fantastic idea for the pet lovers?! You could easily create a kit based on the tutorial above. And you can purchase organic grass seeds from Olive Barn for dogs...
including cat nip!
And they're only a few bucks each!
