Photo - E for envelope

I can't spell, sometimes my mind goes completely blank at the simplest of words. Vowels in the middle of words are my particular problem.

So I make up little rules and snippets to remember...

Like stationery; I always tell myself that the e in the middle is for envelope, that way I don't end up standing still... If you know what I mean.

So I am wondering, what tricks do you use to remember the tricky ones? :) xx
