I have found that students enjoy working on these "Doublets" as a class exercise. I put the two words on top of each other on the board with blank lines (indicating the links) in between them. The rules for these puzzles are that you may change only one letter at a time, keeping the remaining letters in their original position. All of the "Link Words" must be real words that are found in a standard dictionary.

The students will find new solutions, and possibly shorter solutions. Feel free to e-mail me with the shorter solutions, and I would be happy to add them to these pages.
