Found it under fly eye in amazon UK made by think it was Tobor . Small kaliedoscope about 3-4 cm tall.
not suitable for under 3year olds, think most of you will pass. Keep going as first few pages showing a fly mesh for the car.

Amazon search fly eye kaliedescope ...it's there

I have one of those pee holes for a door. It works like a you are explaining. Found it in the hardware store.

Strangely, I bought mine at a stationery store in Georgetown, VA, many, many years ago. I have used it many times to get an overview of a quilt.

Sounds like a great tool?

Hmm, thought I saw one of these at JoAnn's. Will have to check!

I don't make quilts with the same block so I donate the one someone had given me to charity passing it on to someone else who could use it. I thought I saw them in JAF??

I'm pretty sure I got mine in a dollar type store in the toy section. It's a clear plastic thing about 2-3" long, narrow at the peeping eye and about 2" wide at the base. When I got it I wasn't into quilting yet so it was a toy for my sons. Amazing how we find ways to repurpose items for our hobbies.

.....that's it exactly!!!!!?

I've never seen this before. I would love to have one.
