When choosing such items, it is worth remembering that any table sets or pottery will not just be a practical addition to your home, but also an ornamental one, and that you may well be able to find sets that actually improve the look of your home every single day as opposed to only when you are entertaining.
It is also worth considering buying items separately rather than in a pre-packaged set. By doing so, you may well end up paying a small amount more over time, but the set you end up with will be one that is perfect for your own needs rather than one that leaves you with numerous superfluous items, and the cost of finishing your set will be one that can be spread over whatever timescale you like. Consider your lifestyle too.
If you entertain regularly, paying a great deal of money for such items will not be money wasted as such items will need to stand up to regular wear and you will certainly end up getting value for money. For those who entertain sparingly, budgets may want to be reduced accordingly. Finally, consider your storage space. Whilst you may be blown away by a beautiful dinner set, you will not be quite so happy if you find you have nowhere big enough to store it once it arrives.
