How do you give obvious signs of liking a guy?

Please even if the anwser is crazy, just give me an anwser!!!

hang out with him more, stare in his eyes when he is with you, lay on his shoulder when your chillen and there is and od silence, give him hugs everyday when you say hi and when the day is over when you say bye.

touch him when you guys are talking (like on the arm)
flirt with him
give him hugs
try to make plans with him just the two of you
send him flirty texts
but be careful because theres a thin line between flirty and trashy

You could try telling him.

But I get super nervous around him what do I do
