Should I Buy them or Not

I like some western metal wall hangings I saw yesterday in internet store. They look so nice that I had an urge to buy them right away. But the fact is that I already have lovely wall hangings everywhere in the house. They are all chosen by me and are in perfect harmony with all my other decorations. If I buy them I have no where to put hem. It would be inappropriate to do so. I will be sad for them if they stay unused and I can not take down any of my other beloved decorations, because I will start being sad for those I am going to take down. But they are so nice. When I see something nice I appreciate and I want to have it. They are not expensive and it won’t be reckless to buy them, only they will stay in some dark box neglected... Maybe if I buy them and hang them for weak then I get tem in a box and then one week later… maybe this will be a solution…
