A good way to test is either buy the mirror used for this purpose, or put two mirrors together at an angle to see the kaleidoscope.

I haven't purchased it yet but was so intrigued with this material, it jumped into my cart and rode around the store with me.

I wanted something that would appeal to my grandfather but also work for a OBW, wanted to do two things at once. So didn't want anything to wild and crazy he is 80!

My OBW book is on back order, so waiting for it. I can pick up the OBW Encore but was wanting the original.

I will keep looking thanks ladies!

What is the smallest repeat I can use?

I'd say 12". You can double up with a smaller repeat but you won't get as much variation in the blocks. :-D
