In today's wedding world, invitations are no longer just a way of inviting people to your party. The invitation is more like a little sneak peak of what your guests can expect to see at your wedding. The colors and designs you use are very important. You can, and should, use your invitation as the starting place for your whole design concept for your wedding. Weather it is light and fun or dark and elegant, your invitation should speak volumes about what your guests will find at your event.
Here are some great examples of a wide variety of winter wedding invitations. Notice that not all of these invitations draw attention to the fact that it is a winter wedding vibe by using red and green as their wedding colors. Instead they will utilize really rich colors to illustrate the point. You can't have a winter wedding without some beautiful rich colors!
Enjoy being creative!
