Cheesecloth is a loosely woven cotton cloth used in cheese making, and for straining stocks and custards, bundling herbs, making tofu, and thickening yogurt. A versatile cloth, it was also used for shirts during the 1960s and 70s, and for printmaking.

It would have prevented flies from entering through the windows whilst still allowing light to get in.

Geraniums are also known as cranesbills. They are found throughout the hot regions of the world and the mountains of the tropics. These flowers will only grow in soil that is not waterlogged.

Geraniums have large, fragrant leaves which are broadly circular, and their petals can be many different colours.
