You really only need a salad fork and an entree fork. I would just buy the forks instead of making them while playing chess.
Tips on how to get more forks?
Sure, tactics generally come about as a result of a superior position. Your opponent then has fewer options and eventually blunders. Simple, eh? 
I am very close to your level. Or we are close to each other. Which ever the case is our problem, I think, is we are trying too hard to follow principles and exact opening lines and theory instead of just playing. I find just playing as if your new(so to speak) leads to both rookies being confused, thus leading to forks.
Or you can spend hours upon hours studying openings, only knowing openings, find out which opening can produce forks and then, I guess, start middlegames or something.

Umm...no opening can create more forks in the middlegame (although I suppose it seems more likely in open games). If you want more forks you can make attraction sacrifices so that a recapture puts a piece into a forkable position.
Costco sells large boxes of plastic cutlery with enough forks (as well as spoons and knives) for most picnics.
Attack the pawn shop and Costco at the same time?
(Hopefully I don't get knifed for making this comment.)
I, too, have been trying to get more forks over for some dinner parties,
but they are just so tined up with things these days, who has tine for these things anymore?
Some tactics books break problems down by theme. Reinfeld's 1001 Winning Chess Sacrifices and Combinations has a section on forks. With a paid account at ChessTempo, you can create a problem set that has forks as a theme and solve those.
If the "soup eats like a meal" then you'll need a fork
It is rude to eat soup with a fork. If you go to white tie dinners and notice people looking at you and laughing this could be the reason. Either that or you pissed your pants.
Improving one's appearence and status may get more forks. For a common fork, a half decent motor may be good enough...
Joking aside, there's an argument that the "fork" is is actually at the heart of chess strategy and not only tactics. A fork is obviously when two or sometimes three pieces are attacked at the same time.
A fork arises out of superior mobility - perhaps itself arising from control of more space. Superior mobility allows us to attack two pieces or threaten two different strategic goals. The famous Reti king and pawn study study involving a king maneuver that threatens to help queen a pawn or enter the opponent's pawn queening square might be regarded as a positional fork, arising out of the superior mobility of the king.
Further, I think the idea articulated by Nimzowitsch of maneuvering against several weaknesses (last chapter of My System) is a further exploration of this theme.
Bottom line we want to tie our opponent up by creating multiple threats with just one move. This arises out of superior mobility.
I find I struggle to create forks when playing my games. Does anyone have any tips on how to get more forks or some examples of common forks?
