If you find yourself warning, and subsequently threatening, your guests about breaking your expensive wine glasses every time they come over, you may need to put a very small investment into cheap wine glasses.
I know what you're thinking. You don't want to look cheap because you are using cheap wine glasses. You don't have to. As long as you don't go completely trashy and use plastic wine glasses, you'll be just fine. There are many different options on the market today for cheap glasses that will put you out less than a couple bucks each, but still look great and do the job.
There are a lot of reasons to use cheap wine glasses instead of the expensive ones. First the stress level of you and your guests will be substantially lower if you are not always watching for someone who is going to drop and break one, and they are not always watching you watch them in this manner. Secondly, if you have large parties with a number of people, you may not have invested in a larger set of your expensive glasses. With cheap wine glasses you can purchase enough wine glasses for everyone and not be out a small fortune to do it.
So, you're sold on the idea, now you need to know where to buy these cheap wine glasses. The first place to look is in discount stores or lower priced department stores. Often in the home goods section you will find boxed sets of four or eight cheap wine glasses already packed and ready to go. If you are having a big party, you may be even able to find them cheaper if you look for wholesale lots or boxes of them with enough to serve all your guests.
Along with considering your kitchenware options, it is also a great chance to think about the types of wine to fill your glasses.
