Step 1: Variations in Materials
cards vary in stiffness (typically thickness), and that variation needs to be taken into account when cutting into the card.
- credit and debit cards are often the stiffest, and require the deepest cuts to curl properly.
- membership cards (insurance companies and 'clubs' send these out in snail-mail solicitations) are the thinnest and flimsiest, requiring far more shallow cuts. the out-of-control ornament at bottom left of the intro step photo was made from a magazine 'membership' subscription card, and demonstrates why shallow cutting at first is so important.
- gift cards are generally somewhere in between, but the iTunez card shown here is easily as thick as any credit card, so experience will be your best guide.
NOTE : the discount card used in the demonstration was closer to a membership card, for reference.
Step 2: Cutting Order
don't stress : variation in the width of the strips is to be expected. the best rule of thumb is to imagine cutting from the opposite edge of the card, between the strips you are now cutting.
NOTE : remember to cut a bit short of the middle of the card. if the card has not curled by the end of cutting both sides, you can easily correct the curl then. cutting too deep early ... well, ''i've cut this card three times, and the cuts are still too deep !'' shallow cuts are better until you've done your first card.
Step 3: Cutting the Strips, Part 2
this is a good time to examine the cuts to ensure they are nearly uniform in depth.
next, will turn the card and cut from the opposite edge, between the cuts you've just made.
Step 4: You Control the Curl - Don't Let It Control You !
IMHO, this result is ideal ; there is room for adjusting the curl by making each cut (from both edges) end closer to each other. they should not meet, but may pass close to one another.
by adjusting the depth of individual cuts you can adjust the curl at any point along the length of the card - someone will find a cool variation before long, i'm certain.
Step 5: Mission Completed
Step 6: Add Display Hardware
the angle of this photo does not show how cool the card looks, but rather the curl.
