The history of the Advent wreath actually begins long before Christianity.To northern Europeans, a circle of evergreen branches symbolized the endless cycle of seasons, and candles symbolized the persistence of life through the bleak winter. During the Middle Ages, the evergreen wreath became a Christian symbol.  One candle is lit each week, symbolizing the four weeks of Advent leading up to Christmas.

Let's get started. First, gather your supplies.

You’ll need greens, gloves, clippers, four candle holders with spiked bottoms, four blue or purple candles, and an Oasis-brand table ring. I recommend the Oasis table ring as a base because it absorbs water and will keep your greens fresh all through the season.  I’m using a 12-inch ring in these photos, but you can use whatever size you like. If you can’t find an Oasis table ring, you can use a Styrofoam ring from any craft store—though it won’t absorb water.

Let’s prepare the greens. You can use any type of greens you like.  I’m using blue spruce in these photos.You’ll need a few branches worth of greens.  Put on your gloves and cut the greens into small pieces.

 
And remove the bottom inch of needles from each piece.

Immerse your table ring in water, just for a moment. Then, insert the candle holders into the table ring.You want to position them at equal intervals around the ring.

Next, insert the greens into the ring. You want them to lay as flat as possible.

Finally, add the candles. Water your wreath every few days, either by dunking it in a sink full of water or just by sprinkling a little water on it.  Be careful not to place the wreath on an unprotected wooden surface—it could cause water damage.
