After knitting border and proper closing the stitch, you need to wash the shawl.
We need a special agent for washing wool (if it was your knitting material). You can also use a colorless shampoo. Good results are also obtained when using shampoo for long-haired cats. Pour warm water (30-40 C), carefully pour a special agent, gently wash the shawl, without twisting or squeezing. If you have a barbed yarn, you can freeze the shawl in a freezer of your refrigerator: put the wet shawl in the bag and in the freezer for the night. In the morning, put it in a bowl with cold water. The linen is also harsh, but you should be careful with delicate wool, mohair or silk.
Take it out, squeeze a little bit and blot it with a towel. Then, choose a place to lock it: a table, a bed or the floor. (Someone manages to lock it on a hanging carpet or the back side of the couch.) Lay there an unnecessary tissue and put a blanket under it to hold the needles. Give a shape to the shawl, stretching and fixing each corner.
Pay attention to safety precautions when working with needles: keep it away from children and pets.
A finished form of this model should be as follows: the central line should be straight, and the entire shawl should be symmetrical. Pull the corners strongly, focusing on the yarn.

Here you can learn more about it. When choosing yarn, it is important to consider what yarn can better hold the lock. The more synthetics it has, the worse the lock will be. A few photos about locks:
If it did not work right away, wash it again or rinse the shawl and try again.
