Tutorial - Star Transformations

So you don't like Y-seams but love those stunning eight-point stars blocks? Here is a solution for you. The trick is very simple - all you need to do is to modify the LeMoyne Star based blocks to Sawtooth Star (a.k.a. Variable Star) based blocks. Since blocks of the latter category can be pieced with half-square triangles, flying-geese, square-in-a-square and such likes, many people considered them easier to draft and make. 

Do you notice the difference? Diamonds of the LeMoyne Star have edges in equal length, whereas "diamonds" of the Sawtooth Star are made up of two triangles and hence the edges are not equal in length. Also, notice that diamonds of the Sawtooth Star have diagonals meet at one line with their adjacent diamonds and formed four half-square triangles and four flying-geese. That's not the case for the LeMoyne Star block. Interesting, eh? But, keep in mind that though you can eliminate Y-seams, more patches are required to produce the same visual effect. Similar transformation can be applied to more intricate blocks...

The list can go on and on. The only limitation is your imagination.
