Set up everything for a real picnic! Having it in your living room actually feels almost the same as in a park.
Get your picnic basket, make some yummy sandwiches and other nibbles, and include a bottle of your favourite wine.
Arrange everything in a beautiful picnic basket. In the basket, you should have everything you need such as wine glasses, cutlery, napkins and so on (something like this HERE ).
To add an extra touch and create an even more realistic experience, arrange some pillows, spray the room with a flowery scent and play some soft music in the background, something with sounds from nature like birds songs, the murmur of a river or ocean waves.
