Garden umbrellas and folding tents (plain cloth with skipping ropes in 4 Tips to tie in some high points) are the cheapest and most practical solutions, especially for small spaces, because when the sun leaves with great convenience will remove them and leave fresh air free without drown you at evenings, and all sorts of decorative lights you will find in all stores with home–garden items along with some lanterns will add an absolutely summer atmosphere in the garden or balcony.
