Have a plan. It's good to have a plan, no matter what it is about – shopping list, studying plan, work plan, business plan and many other. So, you should do the same with your dinner party – create a party plan! When you have everything written down it's a lot harder to forget something, even if you want to. Every good party planner has a list with the things they need to do, a guest count, the amount of food and drinks, which need to be prepared, the music preferences, important notes, possible risks, how much will everything cost and all that stuff. You can't create a great party without having a plan first, because it's practically impossible for one person to remember by heart all the things which need to be done. So, just write down the most important steps, and afterwards if you think of anything new, you can always add it to the list, and you won't miss anything. The key to the nice dinner party is preparation.
The guests. The guests are another very important part of the party. You practically can't have a party without guests, who will be attending it. I mean, you could, but then people will start to wonder if you're entirely sane. This is why you should carefully consider who you will invite, how many people there will be, and if the space in your home is big enough to welcome all of them. You should also remember to send invitations with options to answer if they will be attending, and don't forget to ask them about their dietary preferences! You don't want to kill some poor allergic to mushrooms person, don't you?
Prepare the space. After you have a plan and all the guests attending are known, it's time to prepare the space and the goods. If you want, you can have a formal or a fun dinner party. Anyway, you will need to pick the right decorations and elements for the occasion. When it comes to the food, you can either pick it yourself or pay a catering company to cook and prepare everything for you. Not everybody can afford the second option though. This is why many people cook everything themselves. Off course, the possibility your oven will get quite dirty is big, but paying an expert kitchen cleaning team is a lot less than paying an entire catering company.
The music. The music is also a very important part of the nice dinner party, since it would be just awkward to listen to everybody chew in silence. This is why you should pick some neutral and relaxing music, which would be liked by almost everybody. Or, if you prefer, you could created a mix with all styles of music, so everybody can be happy. Anyway, the main point is for everybody, including you, to RELAX.
