So who is Jessie Bee?
Jessie wanted to make some small, cute, uplifiting cards that could be given to show a little love. 'The world needs more of that,' she thought.
What are they for?
Bundle them up and hand them over at any occasion, big or small, even just to say 'Hi'; giving a card shows you care. 
Who are they for?
Anyone and everyone. Jessie would be especially happy, however, if they were given to people who are going through a tough time, sometimes you just don't quite know what to say, but a card can make a world of difference.
Why bees?
Because they are great, and the world needs to look after them more. One day, when Jessie Bee cards are making lotsa money (who knows) a percentage of proceeds will go towards saving the dear wee bees.
