Rectangle Pinwheel

Are you ready to break into Rectangles and HRT (Half Rectangle Triangles) ?
This is a very simple block, shown on p. 52 of Collection 2, but I've been unable to find it anywhere in Brackman's Encyclopedia, so ... let's just call it "Rectangle Pinwheel.
Uses Collection # 2.

Fabric 1 (background)
4 rectangles, 1.5 x 3" (cut 2 x 3.5")
8 x 3.5" or 4 x 7"

4 HRT, (p. 134), 1.5 x 3"
3.25 x 8.5"

Fabric 2 (focus)
4 HRT, (p. 134), 1.5 x 3"
3.25 x 8.5"

Print and cut apart the HRT.
Cut away the points along the printed lines.
Layer one focus-fabric and one background-fabric HRT
Join on the long, diagonal seam.
Do this a total of 4 times.
Press.

Join a background-fabric rectangle to each HRT-rectangle, on the focus-fabric side.

Lay out as a 4-patch, and join as a 4-patch.
