Rather than jumping right out and investing in expensive wall decorations, you should make a much smaller investment in a few magazines first. Three of the best magazines for home decorating advice are House Beautiful, Timber Home Living, and Country Living; with a subscription to any of these, you will be in great shape already! All three of these magazines will also give you plenty of great ideas for decorating the walls of your home without spending all your money.
It is also important for you to distinguish between decorating a room so it simply looks "nice" and decorating a room so it looks both "nice" and "like you." After all, something is not guaranteed to make your house feel like a home just because it costs a lot of money! In fact, when items have a bit more character to them, you will actually find that you often identify with them more closely.
Finally, before you ever decorate the walls of your home, a great idea is to establish what the theme will be for each room in the house. This will enable you to look for specifics for each room, with a budget around these specifics, instead of just finding things you like and buying them!
Your house will truly feel like a home once you get the walls in your house decorated; and even though this can take a little bit of work, the work is all worth it!
