Dave, You are correct, it was intended that the word had to begin with the ending of the previous word, I thought another option might include some obscure connections, such as Comet, the link being, that the full name of the Ford car was the Edsel Comet from the 60s , but to save any further confusion we can continue as Ian's original post suggested............
The first posting is a short phrase e.g. shoe lace
The 2nd posting must 'follow on' by starting with the last word of the previous posting e.g. lace curtain.
And so it goes on......e.g. curtain rail etc etc
