[origamiangeltime]

what does it mean when it says 2:1

[jonakashima]

@origamiangeltime It's the proportion of the rectangle. Half of a square

Hi, I did the first grouping of 3 units together to make the first point. But I'm having trouble understanding how to make a group of 5. Please help. Thank you.

[jonakashima]

@creativebeam1 After making the first point, you'll have 3 unused flaps. Chose one and connect two more units to it, making a new point. Continue making new points this way, but you'll notice that eventually you'll have to connect the unused flaps of two existing points. That will happen when you have 4 adjacent points, then you'll join two unused flaps + new unit to make the 5th adjacent point

I have a request!

Can you make some kind of christmas origami for us? Or if you already have one up its fine. But i really want to get my best friend something homemade for christmas. And i was hoping for a origami gift.

[jonakashima]

@AshleyAndElisaFanTv go to my channel, there is a playlist with origami for Christmas on the right side

[Ryuuichie]

its like a variation of the bascetta star. So if you made the bascetta, you can also make this :-)

[mrboomboombop]

ive tried making this but for some reason the flaps where u connect rnt sturdy or anything and i cnt figure out y it wont stay together any suggestions

[mrboomboombop]

by 30 units did u mean u cut 15 squares to make 30? ik im pretty stupid

[Leeanmarjon]

i put a little bit of tapes a the points because it don't hold hard

[Leeanmarjon]

finally!!!!!! i made it!!!!!!

[Leeanmarjon]

thanks to you, because this one gave me some experience of making origami models, even i didn't make it but i completed the 30 modules,i can't interlock them to make the model.thanks also because my mom impressed to me when i'm attempting to build them.....;)

[Leeanmarjon]

you don't told us how to interlock it. so i can't make it right now

[thasito]

@jonakashima pero en centímetros cuanto mide el rectángulo ?

[abdullahmansoor1]
