The half square triangle unit is probably the most commonly used patch in a quilt block -- well it is second only to the square. It is made simply with two triangles, filling up half the square each -- hence the name. Take a quick look through this website, or in any quilting magazine, and you will start to notice that this half square triangle, regardless of its size, is present in more quilts than not.

The Toad in the Puddle is certainly a quaint name for a quilt block. It kind of makes you wonder where these names come from doesn't it?
This quilt block is a simple four patch made using only flying geese units and half square triangles. Colour placement can totally change this block. In this example, I have chosen to make this a very "scrappy" version, but you could easily control the colour placement.
The sample quilts shown use standard settings for the blocks -- one setting of the quilt blocks is straight across and the second is on point.
