Recommend free software for basic flyer design

I have 11x17 pre-printed flyers with a small portion at the bottom left blank to add info. What is a good, free program that will allow me set a blank space (11x17) and let me edit inside of that window? I don’t want anything fancy other than date and time and few lines of text.

Hi…brokenbone don’t need to be worry I recommend you first you try “poster maker” software I hope this is enough but if this couldn’t give you satisfactory result then try another software “Lucid Press” both software I have used before.

Since the poster is pre-printed already, you could just use Word.

Or you could try Affinity Designer or Inkscape.
Inkscape is freeware. Affinity is not, but not nearly as spendy as Adobe.
