I was in need of a laptop sleeve for my computer but wanted to construct my own. this is how to make one easily on a cheap budget.
1. 2 rolls of duct tape different colours recommended
2. Sharp knife or scissors
3.place for cutting e.g. cutting board
4.laptop for measurement
Step 1: duct tape sheet
Take the width and length of your computer
start constructing a duct tape sheet.
a duct tape sheet is made by laying strips of duct tape next to each other adhesive side up with no space between than placing another strip in the middle of those pieces adhesive side down. Repeat this process making sure the length is larger than the computer.
Also when constructing this try alternating the colours of the tape in order to give a nice pattern I used blue and black.
