What you need:

1 straw wreath (30-35 cm in diameter)
corks (70-80 pcs)
4 candle holders
4 candles
holly (artificial)
hot glue & gun

Stick the candle holders into the straw wreath.
Using the hot gun, glue the corks to the wreath and one another.
Insert the holly into the “cracks” between the corks and fix them with the hot gun where needed.
Leave to dry before fixing the candles to the candle holders.

Note: Never leave lit candles unsupervised!
