This block is by Lynne Harris of The Little Red Hen for the Bee Block Blog Hop by Daisy Janie and is called Grandmother's Favourite.
I wasn't too sure if I wanted to make this block when I saw the instructions as it uses lots of triangles joined together. I've made Half Square Triangles using the method whereby you sew two squares together 1/4" on either side of the diagonal and then cut it in half to make two HSTs, but not cutting separate triangles first and then joining them. I've read that it is difficult this way because you are joining pieces on the bias and it is easy to stretch and distort them, but I've also read that using spray starch to stabilise the fabric first helps. So I starched my fabrics back and front, several times, before cutting them and I'm pleased to say they behaved themselves perfectly. No stretching of the bias and no distorting. In fact, I think it is one of the best finishes of a pieced block I've done so far. The seams nested perfectly, and I only nipped off one little tip of a triangle. I paid special attention to how I pressed the seams and managed to get a really flat finish.
I fussy cut the centre square to get a whole rose in the middle.
This is the reverse, showing how I pressed the seams to get a good, flat finish. I know some of the seams are pressed towards the light fabric, but that is the way they wanted to go, so I went with that.
Fabric used is from the Chambray Rose collection by Shabby Chic, Clermont Farms by Moda, and Kona Snow.
