This is actually not difficult to distinguish. It mainly depends on the style of the quilt cover. The methods of distinguishing different quilt covers are different. The first type is that the quilt cover has lace on one end, and the zipper is hidden under the lace. That is, after you zip up the zipper, the lace is put down and the zipper is covered. Of course it could be a zipper, or it could be a strap tied by hand. It may be on one side of the quilt cover, or it may be on both ends. Anyway, for such a quilt, the lace end is for covering the face, and the non-lace end is for covering the feet. Or if there are laces on both ends, then you can tell based on the direction of the laces. Generally, the laces are facing downwards from head to toe. If they are lace facing the same direction, it will be difficult to distinguish. The second type has zippers or straps at both ends, but there are no laces. Usually the end with straps or zippers covers the feet. This looks more beautiful. The third type is that there are obvious words on the quilt, either in Chinese or English, usually in the correct direction. The upper part of the characters is for covering the head, and the lower part is for covering the feet, so it is easy to distinguish. For example, some wedding quilts have the word "happy" printed on them. You can use this method to identify them. It is simple and effective. The fourth type has no lace, no words, and zippers or straps on both sides. How to distinguish this? We can use the pattern on the quilt to straighten the pattern. The top part of the pattern is for covering the head and the bottom part is for covering the feet. Of course, it is easier to distinguish if the pattern only exists in one direction. But what if there are many directions, in all directions. What to do? I will tell the difference based on the newness of the quilt. Generally, the quilt on the foot-covering end is dirtier and older. The side covering the face will be cleaner. Or you can tell it based on the taste. Generally, the more fragrant ones are hijab ones. For example, girls like to use skin care products, and they will also apply some moisturizing cream before going to bed. In the long run, the scent of skin care products or shampoo will appear on that side of the hijab. For boys, it may smell like tobacco or alcohol. The last two methods of distinguishing based on newness and taste are very useful, but of course they are not suitable for newly bought quilts. The above methods are all accumulated in life. It is very useful to practice positivity. You can also try it.
