You can always say that there is such a thing as the perfect engagement present however many times people only think they know what to give and usually give something that is neither useful or ornamental. Engagement parties are a difficult party to plan for but the engagement present is even more difficult to buy or people whom you may not know so well. Normally at the engagement party you will only know one side of the family that means there is a gap in information as to what to buy.
Some easy to think of ideas are available for purchase right here on this website. Items that are used in the home are often the best bet because soon after the engagement the happy couple will be living together. A wedding planner book is one good idea to help them get through the difficult time of planning the wedding. Kitchen goods are great too such as plates and bowls, cups and glasses so that their kitchen will be full without them having to go to so much expense.
Personalized towels for the bathrooms or crystal glassware are other top ideas however they are often done by other and are not so unique. For a more expensive present you could consider his and her watches or simplify with a picnic basket. The old fashioned electrical appliances are another good idea for the engagement present as long as you know that somebody else is not going to get the same thing. Going home with 4 toasters can sometimes just be a waste of effort.
