Another very unusual and creative way of using an old barrel is to basically cut out just a portion of it and turn it into a frame for a round wall mirror. It can have an irregular look or organic shape. The important detail is for one side to have straight lines for the mirror to fit in.
So excited that we'll have outdoor living space at our new place! Will be fun to explore Pinterest for design ideas since we're obviously on a tight budget. I like the look of this "table." A halved wine/whiskey barrel simply turned upside down. -tkz
