I just made this pattern for a baby quilt. As someone else said, the pattern is called Jack's Chain. Oddly, when you are close to it, you don't see the circles; you need to be at a distance.

Who knew that a bunch of squares could make such beautiful circles within circles. Wonderful details.

Thank you to BarbCA.....I did not even think of enlarging it. It shows the pattern perfectly. My eyes were on the quilt so I did not see the note by Lessa Siegele to "Take a closer look"

Wow, this is a beaut! I love how the 9 patches create wheels. My grandmother back in late 1800s made a similar quilt using just blues and creams but no one could find it when she passed.

What a wonderful quilt - I didn't notice the 9 patches until I enlarged!
