I recently gave my sister (she’s homeschooling her kids) all of the extra school borders Ashley and I didn’t use when we organized her classroom a few months ago.
I made her a “school border organizer” out of two pieces of cardboard and duct tape! Worked perfectly, was basically free, and now the borders won’t get damaged or wrinkled when she’s not using them!
The only thing I would do differently next time is somehow make the bottom gusseted so it can fit more!
