Hi Jacqueline,
I looked at your DA page - your work is beautiful! I love your beaded boxes!
The peyote triangle with a hole in the center is made just like the solid top on your triangle box, but instead of starting out with 3 beads, you start out with a larger number, divisible by 3 (so the sides will be equal).
I don't know if links are allowed here - I'll soon find out - but here's a site I came across while surfing. Peetjes' Blog is written in French but the diagrams are easy to understand. She's very generous about sharing her knowledge, and the eyecandy is just amazing. Gorgeous beadwork!

So, no more feeling left out!
