Great quilt top from an online auction, maybe
It's a version of what they call Half-A-Log in Gees Bend,
A Half a Log about 1900
But this one has an extra square in the intersections
and that square is always red.
There's a four patch in the corner.
Not a published pattern
I drew it up in EQ8 using my new repro fabrics
Ladies Legacy from Moda.
The collection has lights and darks and several bright reds.
For a 12" finished block you need to cut 2-1/2 Inch strips.
Perfect for a Jelly Roll.
36 Blocks will make a 72" quilt
Half the blocks have the four patch in the top right;
half in the bottom left. That's the Log-a-Rhythm
I have no idea how many blocks you could get out of one Jelly Roll.
But you probably have a few more 2-1/2" strips in the stash that would work out fine.
