Grow the Plants
I have seen this done with envelopes, gift wrap, and gift cards before, but never with a clothing label! That is such a clever idea. A little garden grown each time you buy a piece of clothing? Sign me up! If you are wondering whether or not these work, they do! I have grown several from the gift wrap.
I also believe that this is excellent for the environment. Discarded tags and labels contribute a lot of waste in landfills, which is terrible. However, if we replace them with planting paper, not only will there be more beautiful flowers globally, but the world will be much improved!
