Awwwwrrrr is right. If you cover it, the pattern will be blurred because of the color change. If the other party can accept the wrong pattern you embroidered, negotiate the price and compensate the other party. If your model is not very complicated, you can be opportunistic, and we can think of some ways to modify it. Try to get close to the pattern that the other party wants! If you can't modify it, you must embroider it again, or negotiate with the other party!

Embroidery is embroidered with thin thread, which is much larger than cloth, so it is easier to cover. But because the thread is too thin, when covering, the tension will sink into the thread you want to cover, which will not only fail to achieve the covering effect, but also make the pattern worse. There is a vague result!
