The main reaction I have received from this sleeve is 'Huh? what's so special about a plain manilla envelope.... oh wow COOL!'...
If you pick just the right color of vinyl for the sleeve, then you will have a sleeve that is visually basically indistinguishable from a plain, manilla shipping envelope while offering your MBA a good measure of protection from drops and bumps and a good measure of safety by obscurity.
Step 1: Materials List
I bought a 6 pack at Target for around $5.00.
Spray Adhesive (Krylon 7010 was used by me but others may work)
Elmer's Contact Cement
4 Sqft of automotive/uphostery vinyl in a color matching the envelope (@ 10.00/yd enough for 4-5 envelopes)
Cutting Knife (better a upholstery knife/carton knife than a Xacto)
Heavy books (enough to cover full surface area of envelope with considerable overlap
2 Red buttons
1 ft Red waxed cotton cord ( purchased 12 ft at michaels for .99)
Thread (the heavier the better)
1 Heavy gauge needle (thick enough to punch through but thin enough to fit through the holes in the buttons with 4-5 threads inside)
Step 2: Cutting
Step 3: Longer Side
Align and place vinyl on flap side of envelope
Press firmly on full surface area with hands, making sure there are no bubbles/wrinkles etc.... Take special care of edges as these are recessed from the surface of the envelope
Place books on top of paper side of envelope whilst envelope rests on a solid smooth surface
Wait 10 minutes
