Like I used a square punch to make all of my inserts, and just laid it on top of my lens cover (I'm not sure if that's what you'd call it) to measure the actual hole just a little smaller.
And I added three little tabs for easy sliding in and out of the inserts. -- Forgive how messy the tape job is...I wanted to be thorough.
I went a little nuts and made a lot of inserts.
But only after I made them all I realized that the designs were too big and didn't photograph well.
Back to the drawing board...
tons of little ones.
And then, this...

My absolute favorite... LOVE

I LOVE IT. (I hope you do too!)
So go on, make your own, have some fun. I'll have to try some actual pictures using mine soon, but the pile of Christmas lights worked pretty well for practice.
P.S. I'm sorry that this was so long!
