hi sweety
in order to make a puzzle, you have to select the words that are the answers first.
like:school-dog-table-etc

then, look what the words have the same letters
like:school-dog
then make the O what combines the two words
like:
d
school
g
and the spaces should be black
that's it!!
its sooo easy
