It's classy and refreshing to serve wine at your outdoor party, but that proverbial fly in your chardonnay is not something your guests will want to worry about. Covering your wine glasses does not have to be boring, but can be a new way to decorate.
Use napkins to cover the wine glasses. If there is an informal gathering or a gathering of close family, keep it simple by putting out some bright-coloured, festive napkins which guests can use to cover their wine glasses. Simply allow the napkin to sit gently on top of the glass.
Create your own wine glass covers using durable card stock paper. You can print a design onto the card stock or draw a design freehand. These homemade covers will rest gently on the wine glass and will be perfect for a party where glasses can get confused. Simply put the name of each guest on the wine glass cover so they can keep track of their glass throughout the evening. These can be made in any shape you want; just make sure they cover the diameter of the wine glasses you will be using. These will also be for one-time use only.
Purchase wine glass covers from companies that specialise in these items. They come in a variety of styles from utilitarian to decorative and can be reused for many years. They will be designed to sit directly on top of the wine glass and keep any outdoor pests from getting into the glasses.
