This is a bit of a teaser - I can get most of it except the middle bit. Any hints?

The middle is supposed to be steam rising from a cup. The three squares on the top of the cup all has a square shaded diagonally to the right of them. Then from there its playing diagonals. Hope it helps :)

Use temporaries and guess -- I could barely solve any of it until I did that.

Thanks for the hint, it really helped.

Thanks, Swanfire - your hint was perfect!!

Multiple answers. :(

The hint was great, Swanfire. I was totally stuck! Thanks!

Thanks for the help!

Everything but the steam was completely logical and they were quite easy to figure out even without the hints :)

The top is also not logical because of the "V" but easily guessed by the title. the bowl of the cup is symmetrical, and the handle attaches to the cup at both ends. Then three curls of steam that zig zag, starting with moving to the right from the 1s attached to the 17.
