The Superman Pocket Shrine
Close-up of the floss holding the Pringle's lid in place
In the scan above, you can see the side of the Superman shrine, and the blue embroidery floss which holds it together.
Plastic--such as the Pringle's potato chip lid--has a "memory," which means that it likes to return to the same shape it was made into at the factory. In this case, the Pringle's lid wants to snap back into a flat position. It's necessary to fasten it at a right angle, for the shrine to look right.
My solution was to use my Fiskars 1/16" punch. I put a total of four holes in the rim of the Pringle's lid: Two on the upright part of the shrine (one hole on each side) and two on the flat part of the shrine (also in the rim, one hole on each side, right & left).
Then I used embroidery floss and an embroidery needle. I knotted the thread as if I was sewing, and pushed the needle and thread through the hole on the bottom/flat side of the shrine. (The hole is actually in the rim, but it's on the half of the lid/shrine that's rests on the table.)
I sewed this from the inside so the knot is hidden under the rim of the lid.
Then I put the needle and thread through the corresponding hole on the top/upright side of the shrine. It's less important whether or not you go from the inside out, or vice versa. Either way, I went through the hole twice, knotted the thread, and left a good tail on it when I cut it. Then I put a dab of glue (Perfect Paper Adhesive, but white glue will work fine) on the tail of the thread, and tucked it inside the rim of the lid/shrine.
I repeated this process on the other side of the shrine.
I know... this is impossible to explain without a bazillion diagrams.. but I don't have time for that right now. Sorry.
If none of this makes sense to you, experiment. You'll probably come up with an even better design!
