Tools: cocoon, pigment, colored pen.

1, according to your own needs, put some cocoons in boiling water for a while to kill the pupae. After processing, a small hole can be cut on one side to take out the dried silkworm chrysalis, and then the incision can be restored with glue. After the silkworm chrysalis is dried, draw a favorite pattern with pigments or colored strokes, which can be pasted in different places for decoration or DIY as a handicraft.

2. Boil the dried cocoons in boiling water and cool them. Open the cocoon by hand, separate the silkworm chrysalis and make a cocoon cap. Generally, 4-5 cocoons make a small cap. The cocoon cap is opened by parabolic bamboo bow, which is convenient for reeling quilt. It is required that the pulling force should be uniform, so as to prevent the uneven thickness of the finished product in the later period, and at the same time clean up the remaining silkworm chrysalis.
