The hey-day of the crazy quilt was the Victorian era, the 1880s and 1890s. Silk satins, ribbon, and velvets, and tons of intricate embroidery, like this one that I repaired a short while ago:
The quilt in the first photo maintains the look of the Victorian quilts, but was made in the 1920s or 1930s. Some of the fabrics are silk (and needed patching because of splitting, just like a Victorian-era quilt). But some of the fabrics are early rayons - evidenced by their condition, and even more, by the colors and print styles.
These next 3 photos show more examples of these things: 1920s-30s-style rayon prints, modernistic geometric embroidery patterns, and some Victorian-like hand-painted flowers. This quilter was really straddling the centuries!
