I didn't have a lot of money to spend and I ended up creating this beautiful wreath for $4. It was so easy even my toddler could do it. In fact, I had to move the wreath because he kept taking it apart and playing with the pieces.
Easy Advent Wreath
1 large plate
4 pillar candles, either 3 purple and one pink or if you can't find those, 4 white work just as well.
Evergreen pieces, Maybe from your tree, the park, or in my case,
Place the candles on a plate, I used a gold charger I got from the dollar store a few years ago. Surround them with greens to make a sort of wreath.
Light one candle each night for the first week, two for the second, three for the third, and four for the fourth week in advent.
Pick a meal or a time of day that you light the wreath and spend some time in devotion.
