I was thinking about wedding registries the other day because a friend just got engaged and asked me where I thought she should register. I told her that she could approach her wedding registry in one of two ways:
1 - Register room by room. Think about the different rooms in your home and create your registry by what you need for each room. So kitchen: Do you need new pots and pans? Do you want to upgrade any appliances. For the bedroom: Do you need new bed linens? Maybe a set for warm and cold weather? Do you need furniture for your bedroom. Etc...
2 - Your lifestyle. If you and your groom love to cook maybe you should focus on great cooking tools. If you love to entertain maybe you want to focus on living and dining room items. If you don't really need anything for your home then register for items that complement your interests.
No matter what you register for it's important to have a variety of price points covered and don't worry about overloading your registry. Better to have more items for guests to choose from then not enough.
