The idea from this came from tv. I saw teh pre-made kit that does basically the same thing i did but I am sure that it costs a little more than what i spent, although the extra time I spent could have easily been accounted for in cash... it takes about 6 times longer to install but at least you dont have to go get it or find it or pay for it.
If you already have plastic wrap and masking tape.
Step 1: Get all Materials together
Wall-friendly tape- anything that dosent leave marks and is removable
Plastic Wrap - uh, any kind of plastic i think..
Electrical Tape - for parts where flexible tape is needed
