I am with others on this thread who have enjoyed the grid-fill, but are now frustrated by what appears to me to be an impenetrable end-game. I have the 13 letter theme and have found a relevant triangle of six letters, but despite being fairly confident as to the shape the loop of lines will create, I cannot understand the instruction in the preamble to "trace the theme's letters, etc.". Does this mean we should use every occurrence of the nine separate letters which make up the three words (I hope this isn't giving away too much information)? If my grid is correct, it cannot mean that we are to use the five letters of the item referred to by the theme because its third letter is not used in the grid. A hint to get me started would be appreciated, otherwise it is going to be a very disappointing end to what started out as fun.
