Many people give out seeds as wedding favors because not only are they affordable, but they're also an eco-friendly gesture. However, keep in mind that not everyone has the space in their home or a yard to grow plants.
You can make the seed packets yourself or buy customized ones online. We found these cute kraft-seed envelopes on Etsy that are selling for $80 per 100 pieces — that's $0.80 per envelope.
