Braille cards aren't for everyone.
Like with my invisible marker, only certain people can read it (easily).
The average onlooker isn't going to pay any attention to the pretty dots on the paper, but to a blind person, or someone willing to take the initiative to look up the braille alphabet and do a little decoding, meaningful messages themselves reveal. ("Love is being stupid... together". Currently available here.)
I made most of these around Valentine's day, but I've continued production because
a) they sell and
b) I like to make them.
That's a very lovely combination.
I only have a couple more in stock in the store, but my head is full of ideas just frolicking around waiting to be commited to paper.
