to make a wormery, take something like a plastic dustbin, drill holes in the bottom about 10 should do it.
Put a good dollop of manure in and make sure it has some of those nice red worms in, put soil on top about one spade full and leave with lid on for about a week, then start putting kitchen scraps in, including cooked food, occationally putting spadefulls of soil in. If it gets wet looking and the worms climb up the sides put in wripped up newspaper, egg cartons etc if too dry add some water. Leave in winter as the worms go into the centre to keep warm and hibernate.
Make sure to have food available for them at all times - kitchen scraps that is.
Keep beside your compost bin.
