The Free Crochet
(It’s google translation) Some tips to weave the bullion or wound:
1. Do not tighten loops when wrapping crochet.
2. Before passing the crochet through all the loops turn them a little towards you (all together).
3. When you crochet the loops, hold them all together.
4. Use a crochet according to the thickness of the strand they are using because if they use a thinner or thicker will catch more easily. Full article with the pattern is below.
