Possible causes of poor quality embroidery and difference of the image embroidery and the image embroidery in the description of the scheme can be explained by:

According to some information the transfer of manufacturing DMC thread to China and reduced quality of dyeing technology, dyes and raw, which is why the thread from different parties have become more different than before.

Using fake threads DMC sale which increases the volume, since there are several full clones cards DMC Chinese production of low quality and cost an order of magnitude smaller, and that's not counting the total clones DMC Chinese production of high enough quality, such as cotton and Royal semisynthetics CXC.

Replacement DMC threads at analogues using correspondence tables thread on unverified sites or programs.

Since some manufacturers already in technology and control dyeing threads laid allowed significant deviation thread colors, we do not recommend to pick up an analog / replacement even on trusted sites, such as the selection of is made on the perfect color analogue and not according to that will get real. Ideally, to assess the accuracy of coincidence colors must be keeping both threads in his hand. (What is replaced and then replaced on that) and do it in a good light.

The accuracy of thread colors required in portraits, ie the human body, especially the face.

When embroidering the body and especially the face is not advisable to use a thread of different manufacturers.

When replacing the threads DMC to cheaper perhaps the best option is to use threads Chinese firms Royal and CXC, which are full of clones DMC cards having the same number threads, although the threads are not significant and different. Threads CXC are the least expensive counterparts at the time of this writing.
