I think that it doesn't matter how you decorate your home as long as it is comfortable to YOU and your family.
I admire the magazines that have all matchy matchy rooms, but I could never acheive that.
I have inherited quite a few things from deceased family members (from furniture to framed maps, old pictures, framed needlepoint, needlepoint covered chairs, crocheted afgans, old table linens, and a few silver plated trays and candle holders.) so my house is defintely eclectic as none of them "match" but they seem to go together or at least to me they do. What's most important to me is that these things give me comfort as they remind me lovingly of the family members that I have lost and I find using their things keeps them "close" if that makes sense. My great aunt had some beautiful table linens she got as a wedding present in the 1930's. They are a pain, because they have to be washed and starched and ironed, but they have delicate blue embroidery on them and I like to see them on the table because they are so pretty. And I do think of her when I do go to the effort to use them even though they are labor intensive to care for.
I have discovered that using paint colors makes ALL the difference in how you pull things together even if you have an eclectic collection of "stuff"
My husband has also made quite a few pieces of our furniture and that also makes a difference I think. Having things he lovingly made for our home along with the family things makes me feel very comfortable and warm and safe in my little house. So what that they don't all match or if they do. It's how it makes you feel that's important I think.
I haven't spent a lot of time worrying over how to decorate my house. I just use what I have and it seems to work. I've gotten several compliments on it, so I guess its ok. I also get lots of questions because I have some "strange" things. We have a family "heirloom" that is a wreath of flowers croched out of human hair. You can't tell its hair until you get very close to it and people find it extremely interesting. I've done some research and this was a "craft" in the last half of the 19th century. No one in my family remembers which relative's hair it is, but we do know that its been in the family since around the 1860's. I've seen like pieces in Ripley's Believe it or not Museum. Some people find it creepy, I like that it's kind of an "oddity".
I also have a picture of my dad landing on an aircraft carrier during WWII. The picture was taking by his bombadier and you see my dad's leather pilots helmet and his shoulder from behind and through the windshield of the plane you can see the entire aircraft carrier as he lines up to land. I have always thought it to be one of the coolest things in the world and its an honor to have it hanging on the wall next to my dad's picture in his Navy Dress Uniform. I get a lot of comments about that picture as well.
But like I said, these people are all gone now and having little bits of them in my home, keeps them close in my heart.
