Here is a puzzle you might not have met before, as it’s one of my own invention. A cross between a Fill-In and a Skeleton which I call ‘Shadowbox’.

Place all the listed words into the grid, crossword style, such that every white square contains a consonant, and every grey square either contains a vowel (A, E, I, O, U), or becomes a black square. The pattern of black squares in the grid is fully symmetrical.

If you enjoy this, I wrote an entire book of them, available online:
