So, half way through my first term my pencil case packed up, a sizeable hole meant that my pens kept escaping into my bag which was a bit of a pain. Most people would have bitten the bullet and purchased a whole new pencil case, but not me; I don't study engineering for nothing, you know!
Step 1: Get the Stuff
Not many supplies needed here. I took the zip off the old pencil case and the orange juice carton out of the recycling. As far as tools are concerned, I used a Stanley knife and my trusty glue gun, but scissors and strong glue would probably do the trick. Oh, also a pen and a ruler.
Step 2: Make the Cut
Trace a line around the edge of the carton then cut it with the knife, remember to leave one edge for the hinge part.
Step 3: Glue on the Zip
Glue on the zip. Sorted.
