Plantable Paper. This is awesome - not only is it crafty and can be gifted, but having the seeds embedded in the paper will keep the seeds from washing away from their planting spot while they take sprout!
Seed Paper at Lazy Crafternoons. This would be great for gifts for friends I think. Cheap. Maybe give with a little flower pot and some soil. Don't forget to include planting instructions so the person receiving these knows they are plantable.
