Give it some time for your concrete to dry and set, again following the instructions. Then you can go about carefully taking them out of the mould. Once they’re out, you have your very own concrete candle holders. There’s lots of room for experimenting with these, with lots of different options for size, shape, colours and even textures. Depending on the size, they’re ideal for holding tea lights or you could possibly even make your own candles to pop in there.
