Welcome to week 5 of the star quilt along.
For this week's block (I'm not sure of the name) I have changed colors because my photos from the first time around were pretty poor. I made this block last night and it didn't go that well. I wasn't in a mood to be quilting (which I didn't know was possible) so that must have been part of it. Anyway, when I sew my block in a quilt top I am going to lose every one of my little points around the outside edge. Oh, well. At least it looks good squared up.
cut each of those squares on the diagonal twice to make 4 quarter square triangles from each square, for a total of 16 triangles from the medium fabric
Once it is all sewn up, square up to 12.5".
Any questions, I'll try to answer them in the comments.
