I love the combination of these two blocks. They create a lot of movement and I keep finding new shapes and designs the longer I look at it.
The first block can be done as flying geese. If I was making this, I would draw the diamond shape and paper piece it to insure accuracy in all of those points. You are right on the second block. It is HST set on point, which makes it look more difficult than it really is.
And I agree with the others -- choose your colors wisely. This will need fabrics with a LOT of contrast. Good Luck!!
