Quilt Blocks 3 & 4

Here are the next 2 Blocks from the online class I am doing with Craftsy 
These are half square triangles - 2 different techniques

Yeah, yeah I know i should unpick that half square triangle - but I don't do unpicking....
Besides it makes the block uniquely mine .....
Not sure if I mentioned it before but I am using materials I bought in the USA in 2005.
