We know your concern: you think you will be a prune if you use a coaster, but secretly, the host(ess) of the party is going to hold you in higher regard because you are valuing their furniture. And this large, but subtle gesture will keep resentment away and the invites returning.
Naturally, people want their wood furniture to appear used, but don’t let it appear well-used on their dime. Granted, it may appear as though it is stain-resistant, but the appearance of disregard is arguably worse than if you were genuinely discourteous. 
Even if the host(ess) is kind truly does not care, if you get in the habit of using coasters when you drink, this will help you not run afoul of another who may place more emphasis on it. 
We can hear it now: “But I’m the host(ess)! How do I incentivize my guests to use a coaster?” Aren’t you thankful you stopped on this page? Because we have the answer for you!
How to use a coaster: 
Here are our suggestions:
• 1 Volume. Buy a lot of coasters and scatter them over all the surfaces you want to protect. This way, your guests will find it easier to just set their drinks on top of the coasters. To purchase drink coasters in bulk, visit our custom coaster printing page to find out more or you can order online directly from our secure shop.
• 2 Dream Bigger. Same concept, different path. This will make it easier to make sure that the drinks with a larger base won’t require surgical-grade hand-eye coordination to ensure that the drink isn’t sitting partway on the coaster and partly on the furniture’s surface (which also can increase the risk of spills).
• 3 Material Composition. Cork or sandstone are highly effective, because not only do they prevent the condensation from permeating, but they don’t stick to the bottom of the glass either. This paired with our first suggestion could be highly effective. 
If you are looking for a more cost-effective method with the same results, cardboard coasters may be the perfect solution for you!
• 4 Alternatives. Say you don’t want to have to bother hunting and collecting the singular coasters – we hear you! An alternative is a bar runner. These are longer, wider, and can protect a greater surface area. These are ideal if you are having a wine tasting at your house or if your guests prefer to congregate around your counters or tables.
• 5 Stubby Coolers. Individual coasters or bar runners are not for you? No problem! Use ultra convenient Stubby Coolers, and slip them on over your drink. Plus, they not only keep your drink cooler, but they look cooler as well. Customize them to match the theme of your event!
We get that nobody wants to be the host(ess) that requests that their guests use coasters, but the longer that you can keep your furniture looking nice, the more parties you can host and without having to replace your stained furniture every few years.
To a similar point, make sure that you and your guests are drinking responsibly. The National Institute on Alcohol Abuse and Alcoholism provides the following statistic, “In 2012, 3.3 million deaths, or 5.9 percent of all global deaths (7.6 percent for men and 4.1 percent for women), were attributable to alcohol consumption.” 
And responsibility goes beyond just your limits. Some drink coasters can be recycled, and the United States Environmental Protection Agency lists the following as benefits of recycling:
- Conserves natural resources such as timber, water and minerals
- Increases economic security by tapping a domestic source of materials
- Saves energy 
By being a responsible host and guest, you are only future-proofing your opportunities to spend time with those you care about.
