Have you ever carefully created a drawing on a whiteboard and then realized you need to change it, forcing you to erase half of it and redraw it?
Here's an approach that will let you rearrange white board diagrams at will!
Step 1: Prerequisites
You will need:
A magnetic white board
A sheet of magnetic canvas (shown)
Dry erase self sticking sheets (shown)
A paper cutter
Step 2: Remove the Sticky Backing
Carefully remove the sticky backing on the whiteboard material.
Be careful to keep the adhesive surface free of dust or grit
Step 3: Adhere the Sheets
Carefully align the square edges of the two sheets.
Slowly burnish the dry erase adhesive sheet to the magnetic one as depicted.
Step 4: Avoid Trapped Dust
If you happen to get a little bit of grit underneath the top surface, you might be better off leaving it there. Detaching and reattaching the sheets can result in creases, like the one in the second photo.
Step 5: Cut Into Assorted Sizes
Using the cutting board, cut the dry erase notes into assorted sizes.
Step 6: Enjoy Your Relocatable Thoughts!
Now you can lift and replace key ideas without having to redraw them!
This could also be useful for UML diagrams, if you're into that sort of thing.
