I'm sure there is a better way...
I stamped the bugs, fastened them on a T shape pull, the Ruby Red is the top of the T. I only fastened the very bottom edge of the bugs, then I slit right at the top of the pocket, slipped just the bugs through and the rest of the T was behind the card. I added the slit punch half circle at the top to make it easier to pull out.
I only taped part way up the sides of the card to make sure that I had enough give for bugs to move.
I think next time I might add some eyelets to keep everything together a little better.
