[blparent] braille blocks

[Stephanie Mitchell]

About 4 years ago, I bought some braille blocks from 
blindbookstore.com
However, the braille seems to be fading a bit, and I was 
wondering if there are others out there.  These blocks have the 
print letters, which are raised, with braille letters on them as 
well.  I used these to teach 2 of my children the alphabet, and 
want to have a set for my youngest child to learn.
Also, are there flashcards in braille? I like those for teaching 
colours and shapes.
Thanks,
Steph
