Having trouble with your To-Do list? We love this Post-it Pillow concept from Veinticuatrodentes (Spanish for twenty-four teeth!) Taking the Post-it note to its natural conclusion, these comfy cushions are coated in a special something or other that lets you write AND erase, using a clever water soluble marker. (Included for $24!). What better way to jot down those midnight brainwaves than directly on the pillow your brain is lying on!
