We need a template for our educational worksheets. These are STEM (Science, Technology, Engineering, Math) activities. This will include developing a template cover sheet, a (sort-of) letterhead (like the border/design around the pages), choice of fonts, borders for graphics, etc.
Note that these sheets are designed to be printed: SO although you can use color if you wish, they should look good printed in black and white.
Graphics should feel Timeless, Retro, Vintage, Classy, Light
Childish, Kid-like, Heavy
