Use stationary (with an "a") when something is not moving; use stationery (with an "e") when you mean paper, envelopes, or writing supplies.
Definition: stationary
Stationary is an adjective that means "not moving" or "fixed in one place." It describes objects, people, or systems that remain still or are designed to stay put.
Etymology: stationary comes from Latin statio ("a standing place") via Old French and Middle English. Think "station" — something standing still.
Definition: stationery
Stationery is a noun that refers to writing materials such as paper, envelopes, pens, and sometimes greeting cards. It also includes business letterheads and note cards.

Memory Trick
Mnemonic: stationery has an "e" — think "envelope" or "e for express yourself on paper." Stationary has an "a" — think "at rest" or "a" for "anchored."
Quick tip: If the sentence involves movement or lack of movement, use stationary. If it involves paper, pens, or letters, use stationery.
Another small habit that helps: when you write, insert a mental cue. If you picture an envelope, type the "e" in your head before you type the word.
