I guess the second half triangle is sewn on last?
When you join the blocks, you are joining the half triangles, hence the seam allowance. Just remember to alternate the light and med/dark blocks to get the effect.
Thanks maviskw, for a good idea.
You've almost got it! What I forgot about is that you have two different blocks. The white stripes and the colored stripes lay in different directions. One slants to the right and the other slants to the left. So for the whites the triangle beginnings are put on skinny side up on the left side and fat side up on the right side. For the colored blocks, the triangle beginnings go fat side up on and left side and skinny side up on the right side. I found it easier to do all of one color-way first, so they all laid the same way, and then do all the others that will lay the same. And I made my triangles 60º. Most rulers have the 60º mark on them.
I have actually made one now, and it turned out beautifully. A lot of people were asking me how I made it.
