I get the feeling I've seen this somewhere but can't figure out where.
Anyhow .. My sweetheart was going to school and needed a case for her glasses, I didn't have one so I made one. Turned out pretty good.
Step 1: Ingredients
You will need :
1 piece of cardboard with stylish printing, I used a folder I got from some endorsement for a town.
1 pair of scissors (or is that two scissors?)
1 roll of duct-tape
Extras : a pair of glasses or the longest pen you're gonna put in.
Step 2: Measuring ..
Cut the cardboard to fit the glasses or something .. remember to roll the board rather than folding or creasing it.
Step 3: Sticky Stuff
Put the tape along one end and stick it to the other end to form a tube .. sortof.
Step 4: Seal One End
Seal one end with ducttape.
Cut off any excess tape.
Step 5: Folding
Bend one side of the opening inwards and make a round crease.
Do it on the other side of the open end as well.
This forms the lid.
Step 6: Alternative Design ..
For a box don't tape up the cylinder .. instead make the lid-creases on both ends and tape one of those up.
Also .. contrasting colours on the ducttape, cardboard and print are nice.
Simple looks very modern I think.
Courtesy of user Patrik who made a good suggestion :
To get a cleaner crease, you can try pre-creasing it using a cylinder of some sort. Something hard and thin-walled would probably work best - you can probably find a tin can (empty or full) of just the right size.
Put your cardstock upside down (or rather outside-down) on something with a little "give", like a stack of paper or a rubber mat. Mark on the cardstock where you want the creases, line up the can with the marks, and press down hard (or even tap with a hammer, if you think your cylinder can stand it). Experiment with different diameters to see what gives the best result (it's only cardstock after all...)
