that is only one way to do it though. You can use herbs, incense...anything with a magical property. Do what feels right, but make sure you do your research on the materials of the spell you are using.
Majority of wish spells are quite simple and ancient since they did not change a loy since even Middle age .
You can catch a falling leaf and say a chant , wish what You want and keep leaf till it fulfils .
You can toss a coin into wishing well and sprikle some catnip . Say Your words of power and ther You go.
Write Your wish with dragon blood on Laurel leaf at new Moon , place it in bag , sachet or bowl with dryed lavander and on the night of the Full Moon burn the leaf.
But before all ( and no offence ) Learn Your basics , before You ask for ( paraphraseing ) Real spells that work. Magick is not just a collection of formulas it is a Path ok knowledge and revrance.
That reminded me of a ritual for pelasent winters Obscurus. If you can catch an Oak leaf falling from a tree (The leaf still need sto be green) then you will have a pleasent winter.
If you believe in the sky that they can deliver your message, if you believe that anything could happen if it is a simple request, any wish can happen if you believe and make your wish a simple one...
Dont wish for a boyfriend or a girlfriend, Money, Power, A Sports Car.... Only the gifts of wisdom and small matters shall be Granted... Also if it is to save a LIFE...
Or the wishing on a poofy dandelion, or fallen eyelash before blowing them away.
You can also write your wish(es) on a slim strip of paper and fold it into a star. You can hang it from a tree, bush, windchime, whatever and ask a certain deity (or creature, being, whatever you believe in) reads it and helps you.

And then there is the beloved:
Star light, star bright
First star I see tonight.
I wish I may,
I wish I might,
Have this wish
I wish tonight.
