Here's how I made mine.
You'll need (24) 2.5" x 2.5" squares. This is a great time to fussy cut if you want.
Strip-piece (12) of the squares to 2.5" WOF, strips.
Cut the units apart and press toward the print.
Still stip-piecsing, attach a 2.5" strip to the side, and cut apart and press. In the original block, these were 4 patches, I change them up because it was more logical, to me.
Take the four remaining units, still using the strip-piecing method, attach a 1.5" strip to the right and left.
Cut apart, and press to the center. These units were not in the original block, but I thought they were necessary to keep the movement going for the outer circle.
You're almost to the end of the strip-piecing. For the remaining units, attach a 1.5" strip to all four sides. Do this a step at a time. Attach a strip, cut apart, press, and repeat three more times. Left, right, top, then bottom.
Lay the blocks out for final assembly. I first put down the inner circle, 9 patch, then the outer circle, making it a 25 patch. You can see there was one more patch, a plain 4.5" x 4.5" square, for the center.
A couple of more photos of the block. The block measures 21" x 21", so it will finish 20.5" square.
May your bobbins always be full,
