Narrow stripes, known as neats in the fabric industry,
were a fashion necessity after 1860 or so.
Like this madder-style stripe in my newest Civil War reproduction collection for Moda.

1862 Battle Hymn is in shops in the precuts including Fat Quarter Packs.
This particular stripe comes in five colorways
I named the prints after Civil War battles from 150 years ago.
The neat stripe is called Cedar Mountain.
This colorway with it's madder reds and dulled oranges is named Culpepper Peach.
The navy blue at left is Farragut Blue and the lighter, steel blue Merrimack Blue.
There are two neutral (what we might called taupe) colorways---on the left Stonewall Gray and in front Sharpsburg Tan.
The blues and the neutrals are rather subdued, evocative of the national mood in 1862 when everyone began to realize that the War would be a long and horrible conflict.
Roseanne Smith has some 2-1/2" Jellyroll strips and some 10" Layer Cakes. She's been busy with the neat stripe in the peach colorway.
She loves to miter
I could see a whole quilt out of scrappy nine-patches with mitered frames.
I'll post more about the prints, colors and themes in 1862 Battle Hymn. The yardage should be out any day.
