Here's the perfect photo, Oliver Mills and his dog...
And a quilt.
The patchwork design seems a little chaotic but it's not. It's a complex pattern.
With two components.
The center of the block is a simple wheel/star.
I haven't seen that exact design before but I drew it in EQ.
Each of those wheels is framed by diamonds.
You see the diamond frame often although this configuration
doesn't have a BlockBase number. It probably should be 2065.5
When you set the blocks together you get a diamond star
and a large white square with no seams for some fancy quilting.
Quite common in the 19th century.
But you could frame anything with those diamonds.
Creating a very complex design.
The Dog Star?
