So you mean "HOW" right you haven't given any topic if you had I could have written the whole poem..:)
so like 1st point your poem should have rhyming words in each sentence I mean do not write like 1 line rhyming word 2nd line just like that 3rd line again a rhyming word... no!!!!!!! not at all! and if you can't find rhyming words then do like this
eg. THE WORD IS- WEATHER
so try this
aether, bether, cether,deather, FEATHER, .........
so that will help try like this ABCDEFGHIJKLMNOPQRSTUVWXYZ..
and try to write a happy poem not a sad one coz you are making yourself right?????? so you will also not like sad poems..won't you?
TRY TO MAKE THE POEM FUNNY EVERYONE WILL APPRECIATE YOUR HARD WORK!!!!!!
HOPE THIS HELPS!!!!!!!! THANK YOU :-D
