I was surprised to find out that many teachers are out-of-pocket for school supplies if they don’t happen to take the generic stuff that every other teacher can hand them instead of throwing out.
Then it hit me: Heromachine 3 is probably a very easy way to customize school supplies. All you need is a good printer, right? Let’s say you need fifty sticky gold stars (I HOPE a teacher would need that many.) Get sticker stock paper. Magnify the American flag found in Backgrounds. Stars to gold, other colors to 0%. Cutting you’ll have to do yourself, but they can be any size you can magnify to on your photocopier.
What about teaching other shapes? The easiest thing in hm3 is to go Insignia/Tech or /Shapes for all the basics. Then change ‘single’ to ‘multiple’, select more and ’tile’ them however you need them on the page in Transform.
