I used Toho Treasure again - gold lined aqua - and I must say that I didn't expect them to look so good in a beadwork. Depending on the light they look like a cold steel or they have a warmer, yellowish tint. Worked good with some antique bronze seed beads, I think.
The triangle measures 6,5 cm (2.5") at the widest point.
The tutorial is available here on Etsy.
Now I have to go back to work... I promised to prepare the tutorial for the twisted square too...
Have to keep my promise, you know! ;)
So I'll see you some other time. Have a wonderful day! :)
