These are 2 of the 3 afghans I made for our United Way Campaign last year. Different people donate items and then we have a not so silent, silent auction. The one with the trees I got out of one of Vanna White's pattern books. It is crocheted using 2 strands of yarn.

The snowflake afghan I got the pattern online at http://www.artoftangle.com/snowflake.htm

Very quick and easy.
