How to hook the concave lace of hexagonal clothes?

Tighten crochet, increase crochet quantity and adjust crochet length.

1. Tighten the crochet: wind a circle of thread on the crochet, pinch the coil with your fingers, put the needle at the tiger's mouth, and push it from outside to inside, so that the coil stays at the tiger's mouth and the crochet is inside. This will make the lace smoother.

2. Increase the number of crochets: wrap a circle of thread on the crochet, pass through the first circle of thread, and then wrap it again, and so on to increase the number of crochets. This will make the lace flatter and fill the concave part.

3. Adjust the length of crochet: wrap a circle of thread on crochet, pass through the first circle of thread, then wrap a circle of thread, pass through the second circle of thread, and so on to increase the length of crochet. This will flatten the lace and flatten the recessed part.
