Very entertaining and informative! You've gained a new subscriber. Near the beginning, you showed one (looking quite polished), then pulled it apart to show the triangles. How did you do this? Had you not glued the ends or were you using magnets or just holding it carefully without those pieces being adhered?

Hi! Thank you for your nice comments. The triflexagon at 1:20 is made from card and the two triangles that have to "stick" are held together by a tiny piece of blu-tak. I also have a much bigger one held with velcrose, but it's not so easy to use. Good luck if you're making your own!

@@murderousmaths Thanks for the prompt reply and for your instructions and PDFs with designs. I've become fascinated by these and have now made several flexagons, including many of yours. I tagged you in my YT video, but here's the link in case that didn't work: kzbin.info/www/bejne/gmTIZHp-jrurpKs Thank you again. All the best.

Truly enjoyed this video! I think I saw how to make one of these on your website, I’m not sure.

Thanks! I love flexagons and I've done several videos about them so you may well have seen one of the others. This is the first one with the "Witches Purse" which is one of my very favourites!

I saw your hexaflexagon and triflexagon. They moved very smoothly. In particular, the color of Hexaplexagon was very neat. Besides, it was big. How did you color and what paper did you use to make the flexagon? Also, the hexaflexagon was not thick and well made. How did you do it?

[@murderousmaths]

The bigger flexagons are made from card, and they move smoothly because I've shown them at 100s of events! The colour bits are mostly coloured printer paper cut out and glues on, or stickers. The smaller flexagons are drawing pad paper, slightly thicker and tougher than printer paper.

@@murderousmaths Thank you! It was a big help. Have a nice day!
