I printed the directions out. Who knows I may even get around to making one soon.

First I Best Press my material before cutting. I do use Jodi Barrows Square in a Square ruler ... just not her technique. Whatever size SiS I make I figure out ahead of time what size triangles to use so that I do trim off just a tiny bit.

The Sis ruler helps with the seam allowances when I put them together.

I bought Deb Tucker square in a square ruler and have never regretted it!

Before I had the Go, I just made the square in a square using hsts.

I have the square in a square ruler also, it works very well

I agree, try the SNS ruler and technique by Jodi Barrows...really works!

bearisgray is correct - I always aim for the straight of the grain along the outside edge. Also, YES I always make mine larger and trim to size each time.

In a pinch, I fold the triangle point to point and gently finger press. Same thing with the square. Be sure to press them in the same direction and don't stretch. When you put them right sides together, they nestle. Its not perfect, but its gotten me out of a jam a couple times!

Never tried one, but mine would probly be wonky too!

It is absolutely necessary to square up your block before adding the next round of triangles.
