I remember when Shrinky Dinks first came out in the 1970s... I thought they were very cool! You'd get a few sheets of the plastic, plus coloring pens and some illustrations on paper you'd trace and color on the plastic. Then you'd cut 'em out, pop 'em in the oven, and the plastic would shrink down to about half the original size and get thicker at the same time! An enterprising friend and I took some of the sheets, traced a Darth Vader head onto 'em, used a paper punch to put a hole in the top... and after the oven time... presto! Darth Vader pendants! I don't recall if we actually sold any of them or not.
Never did get the set pictured above, though... I do have to wonder why it didn't occur to me to trace pictures from the comics!
