Step 1: Materials and Cutting the Cardboard
cm Ruler (cause thats how I roll)
Thin Cardboard (I used the back of a spiral notebook)
Rubberbands (see how its plural? you need 2+)
Playing Card Case
Cutting the Cardboard:
Using the Playing Card as a template, cut out two 6.5cm x 8.8cm rectangles.
Next cut out two 1.2cm x 8.8cm rectangles.
Step 2: The Notches
These are the notches for the Rubberbands.
On the Playing Card-sized rectangles, make a 2cm x .5 cm on each corner. Upon finishing, cut the .5cm edges out (cut out on either side of the drawn line to achieve a good sized notch).
Step 3: Inserting the Rubberbands
Put the Rubberbands in the Notches to acheive this: (look at the pic, look long enough and you'll understand, look longer and you'll see which games I own)(sorry about the lack of decent/informative pics for this step)
Step 4: Putting It Together
Tape the for pieces together in this order:
Sm rectangle - Lg rectangle - Sm rectangle - Lg rectangle
Tape above the notches on the front and back. Also tape the rubberband on the back side so it doesn't come out of its home.
Step 5: Last Step
Fold the case to put creases in the tape.
Insert case into the playing card case.
Playing cards for the case? I haven't tried it but it should work.
Different case? As this is only my second attempt, I haven't tried that either.
Different design? I have thought of an I-beam style design, but haven't put it in reality form, yet.
EXPERIMINT!!! Try different designs, cases, games....(UMDs should work)
