i pasted mine just 1 day earlier, so it will look new on wedding day... In fact, for the 'xi' outside my main door, i pasted it like 1 hr earlier, coz i scared wait some strangers disturb and tear away before my wedding.. =p
anyway the "xi" at my front door is still there after 1 month. dun think anyone will be so evil to tear away before my wedding, but better be safe than sorry...
