This is a close-up of a soft, fluffy knit sweater fabric.
It features a two-tone design with wide bands of pure white and a patterned section in light blue and white. The pattern is a distinct zig-zag or chevron knit in the light blue color, separated by thin, slightly shimmery white threads.
The overall texture is very cozy and plush, suggesting it is made from a warm yarn, possibly a mohair blend or brushed acrylic, ideal for winter wear. The top edge suggests a high-neck or turtleneck collar
