One Sunday while i was watching my grandmother's sewing machine it came on my mind to build a simple modern Sleeve for my Macbook Pro 13.3". The materials i used was what i found lying around. An old pair of blue jeans and a piece of durlap in the store room used for sack repairing. It didn't take more than one to two hours to learn how to use the sewing machine (by reading the manual and some videos on youtube) and cut the materials in the correct form.
Here is the result of the unique Candrian Sleeve
I used the bottom of the jean as a pocket in the Sleeve
