Personally, I think it has no collection value at all. There is nothing to be proud of except for its large scale and famous paintings, and naturally it has no collection value. Then, from a technical point of view, cross-stitch has no technical difficulty, except that it takes a little time, and it is also relatively common. If you can master the techniques as soon as you learn, if you use some embroidery method, such as Suzhou embroidery, it will be of little value. If we use more precious and rare skills, such as silk reeling and brocade, it will be of great collection value, because this endangered skill will have a lot of room for appreciation after 20 years.
The collection of embroidery works of art depends not only on embroidery techniques, but also on craftsmanship, such as cross stitch. There is not much difference between good and bad, but other embroidery categories, such as silk reeling and brocade, are not only valuable in themselves, but also good or bad in workmanship.
