Comparison between machine embroidery and manual embroidery

‌Threading and stitches‌
Handmade embroidery‌: The length of stitches is flexible and can be adjusted dynamically according to the pattern; the threading has arc changes and is delicate and flexible. Silk thread can be split to the thickness of a hair (such as 32 strands), showing multi-level gradients.
‌Machine embroidery‌: The stitching length is uniform, and the threading is straight and rigid; the embroidery thread is made of chemical fiber, with a fixed thickness and lack of layering.
‌Color and three-dimensional sense‌

‌Handmade embroidery‌: Natural silk thread has its own luster, and the color transition is natural (such as animal hair gradient requires dozens of intermediate colors); the front stitches are breathable, and there are few connecting lines on the back.
‌Machine embroidery‌: The chemical fiber thread is reflective and stiff (commonly known as "thief light"), with ≤5 colors and abrupt transitions; the back is densely covered with connecting lines and feels stiff.
