Unfortunately, you cannot make a Party Hat (of any colour). They were given out when RuneScape first came out.
I'm afraid you can not make a party hat.
There is no way to make a partyhat in RuneScape. This is an item from a past seasonal event; it is not made any more. If any player could make a partyhat, they would NOT be worth a billion coins each.
13498 i think
Blue partyhat costing 2100M
Currently, at over 2,000,000,000 coins, is the White Partyhat.
Well, I wouldn't exactly say 'make' a partyhat but a new partyhat can be introduced to the game by cracking a Christmas cracker. Sadly, it is not possible to introduce new Christmas crackers to the game so the price for crackers will never drop again unless it is possible to get new ones.
RuneScape private servers are illegal. If you get caught using one, Jagex may choose to prosecute. Do not use them!
Why should it? The partyhat was a one-time-only prize for a special event (actually it came out of a Christmas cracker, which was awarded for the event). There is no way to make a partyhat now. If somebody tells you he knows of a way to make a partyhat - well, it simply isn't true.
Yes, they were given out in crackers in the 2001 Christmas event. No. Anybody can buy a partyhat - member or otherwise.
Either a partyhat, or a Christmas cracker - check the latest prices, they tend to change.
There is no way to spawn blue party hats in runescape. However the item code is either 1042 or 1043 for use on private servers.
the most expensive: blue partyhat the most useful combat weapon: corrupt dragon scimitar
