Undercover Laptop Case

Step 3 Trim to Fit

You'll want to trim the excess cardboard, so that your laptop fits just snug when the case is folded up. Leave a little room, but not too much so that the laptop will not bump against the walls when you are carrying it. Draw guide lines so that your cuts are straight. Cut off any extra panels on the top flap. Measure the bubble sheet and the trim excess to fit the cardboard.
