January Phenomenon

There's a strange thing happens at this time of year.
 It happens most years and almost exclusively in January.

This is it -

The jigsaw.

I finish one

then carefully pack it away.

Making sure to store the edge pieces separately. I don't want the tedious job of sorting them out the next time around.

Then I'll do another

This one is dated on the box -1983.

Then I store away the puzzle board, ready for next January.
Phenomenon over.
