Beds, blankets and pillows: yes. Sheets: no, except if someone is coming outside Finland.

Someone said he could make pizza. I suggest one meal could be "Mättöpelti" with meat and nachos and some weggies to throw with. Then chicken salad and something to barbeque. If people come already on friday, I would suggest something easy to barbeque. Then breakfast stuff (bread, cheese, cucumber, meat, yoghurt, juice). If people come only from sa-su, there would be lunch, dinner, evening meal, breakfast and lunch.

Everyone should bring their own alcohol drinks yes. If some kind of wine box is needed someone else should bring. I don't know about wines. Also maybe better everyone brings their own beers, or what do people think? We can buy also together but tastes differ. And shared expensies.
