Being a new house owner (two years and counting...) definitely led me to a decorating frenzy. The satisfaction comes mostly from finding things that don't break the bank but give the most impact.
Some of my new favorite buys...
1. A4-frames, that i use to display a collection of old money and stamps, as well as some quirky illustration cut-outs from magazines.
2. Tin cans for storing stationeries
3. Fold-able shoe-rack that saves much more space by allowing each pair to be put on top of each other.
4. Trays for grouping of things and hence give a neater look to the tables. I have wooden, rattan, aluminium, and now, steel.
