These are computer generated pictures not actual quilt blocks. I posted a Sampler Quilt Along last year and there are 84 of my original designed quilt blocks using my shortcut methods in the Quilt Along.
You will see all of the weekly threads with the quilt blocks here and each one has a layout to show you how to place the HSTs to make the quilt block.

I am hosting a quilt block swap using my designs and was asked if I had any HST designs. So I pulled all of just the HSTs into one thread to make it easier to see them instead of having to hunt through all of the Quilt Along threads for them.
