Click here for pin-spiration! This is a four-ring version similar to the "great granny" block by Lori Holt, as it also uses extended edge pieces to make sure that you have enough room to trim the block to 12.5 inches. This one is a great one to pick out any small scraps you might have left over from other blocks thus far and use them up without cutting into more fabric.
Two (2) 2.5 inch background squares
Fourteen (14) 2.5 by 3 inch background rectangles
One (1) 2.5 inch square for center
Four (4) 2.5 inch squares for inner ring
Eight (8) 2.5 inch squares for middle ring
Twelve (12) 2.5 inch squares for outer ring
Here's the cutting diagram plus the block layout.
Sew together squares in diagonal rows. Your longest row should be capped by the 2.5 inch background squares and the shorter rows should each have a 2.5 x 3 inch background rectangle on the end. Iron rows in opposite directions.
Sew rows together. Seams of each row should interlock if you alternated the direction you ironed each row. Press connecting seams -- I ironed mine from the center going out. You may want to iron these seams open if you find your block is particularly bulky.
Square up your block to 12.5 inches and voila! You're done!
