The clue words should be in uncontracted braille (in the braille file attached).
As for the answer. I've used the method of stating something like "the word TEXTURE begins with the 2nd letter in row 1 and goes across the page". But that was when there was only 1 answer given. This method could still work for your answer puzzles. You could do an overall TN that states word placement is in a TN following each word (or something similar to that) and then have a list like:
TEXTURE tnrow 1, letter 2, acrosstn
PROPERTY tnrow 4, letter 9, downtn
There is, obviously, no BF rule about this. It does follow a similar format as the crossword puzzle which has the overall explanation TN and then an embedded TN after each clue.
