I couldn't find this classic make-a-snowflake site when I was hunting links for the Monday ten, but rediscovered it over at Larissa's place, along with a virtual snowglobe (as Larissa advises, watch what happens to the snowman builder.)
Quick holiday centerpiece for any table: fill a pretty bowl with red (Rome, Red Delicious) and green (Granny Smith) apples, or whatever leftover glass ornaments you have from the tree, or different-sized pinecones sprinkled with fresh cranberries.

The best generic adult gift: Books. Other than books, a basket of scented candles of various shapes and sizes. Both genders seem to like forest, spice or sea scents.

If you go to a candle shop, they usually have baskets already made up.
The best generic kid gift: Books. Other than books, Etch-A-Sketch (younger kid) or the Magic 8 Ball (older kid.)
The best generic writer gift: Books. Other than books, bookstore gift card. Don't make us beg.
