Puzzles are a great way to gather friends and family into casual conversation. Put that old card table to use in a corner and fill it with a puzzle in progress. It is amazing how many people will gravitate to it - "just to put in one piece". (And of course, they will stay awhile!) :-)
The holidays are a time when puzzles are wonderful at helping to balance the hectic pace to be slower, more comfortable, and enjoyable as you slow down and take things easier.
Puzzles are especially great to take to the cottage, where the challenge of a puzzle can be met with relaxed intensity.
