I was covering for another teacher this morning so that she could go to her daughter's 6th grade graduation. While I was watching her middle schoolers taking their final exam, I started sketching out some plans for a monarch butterfly block. I went through several iterations before settling on a simple flip and sew four patch variation.
You will need to cut:
From orange (wings):
2 rectangles each 3 by 2.5
2 squares each 2.5 by 2.5
From black (body and wingtips):
1 rectangle 1 inch by 3.5 inches
4 squares 1.5 inches (the photo only shows 2, but you will actually need 4)
From background fabric:
1 inch square
1 inch by 1.5 inch rectangle
2 squares - 1.5 inches
4 squares - 1.75 inches
Draw a diagonal line across the hypotenuse of each of the background squares except the one inch baby square. Also draw a diagonal line on the black wingtip squares.
In case you have trouble with flip and sew triangles, I can recommend leaving the background square in tact, at least until you are sure that the edges line up. Just use the orange square as your master sizing guide and trim away any extra of black or white that extends past the orange.
Place the body in the middle and sew one wing to either side. This is where everything would work out perfectly with a nice press. I'm sure my iron will turn up any day.
