Fun with Half Square Triangles

I made diagrams for a 9 patch block, 16 patch block, 25 patch block, and a 36 patch block. All the blocks are made from half square triangle (hst) blocks and squares. The blocks are put together without any other blocks or sashing and different shapes appear between the blocks.

The first block is very simple. It's made of 4 white squares, one colored square, and 4 hsts.

Put a few together, and a gorgeous quilt is formed.

It looks like you made some pinwheel blocks and put them together with sashing when you really didn't do that at all.

The next block is made only from hsts and no squares. Just the block contains a pinwheel and a star, but put the blocks together and you see even more.

Another star appears but it has an on point square inside instead of a pinwheel.

Next, the 25 patch. It has 4 color squares, but the other 21 squares are all hsts. This one looks great with a few put together.

All the circles are connected, and pinwheels form at the corners.

Finally, the 36 patch. This one is my favorite of all the blocks. Especially when you put several together for a quilt.

I love how the stars and the pinwheels are framed!
