Keep Calm and Spell Check (with errors)(any color) Square Sticker
This is the classic war poster "Keep Calm and Carry On" still with the original crown at the top. It's reworded to "Keap Carm and Spell Check". It's a funny design that makes perfect presents or gifts for teachers and students alike. Not to mention editors and writers, anyone who works with words. It's a great poster for your classroom, or study hall too.
I've put this on a blue background, but you can change that really easily. Hit 'Customize it' and then 'edit', and you'll be able to change to absolutely ANY color you prefer.
This design is available on many many products, and I have lots more 'keep calm' variations to explore (including other variations of typoes/proofreading mishaps).
