Prep for next four blocks, the corner blocks.

 

After cutting focus fabric and background fabric it is layered with the sewing guide paper, Triangles on a Roll.

Cut on the solid lines, and now I have 24 half square triangles.

Next remove paper, and then press open the seam lines and trim "dog ears".

Now to lay them out to start sewing. These four will be in the same setting, Ribbon Star Block.
