Block 10 Carolina Lily with No Inset Y Seams

Martha C.'s block

She modified my pattern by adding seam lines,

thus subtracting Y Seams.

She added seams in the top half.

This is the original pattern with B and C requiring set in seams.

I drew up her pattern in EQ8. The pieces have new letters here.

For the large background triangles A

Cut 3 squares 4-1/4". Cut each in half diagonally to make 2 triangles. You need 6.

For the small background triangles B

Cut 2 squares 3-3/8". Cut each in half diagonally to make 2 triangles. You need 4.

UPDATE

Wait a minute.

You have to do this too.

The largest triangle is now cut in half and is the same size as A.
