African Collection Senegal Twist is a pre-twisted item so we would advise to use a crochet needle hook for a better result. This is a half folded item so excellent for a bulky result.
If you are interested in crochet braid item for a flatter finish, we would suggest the following two pre-looped items in our X-Pression collection:
X-Pression Senegalese Twist Small
X-Pression Senegalese Twist Large
