Love them, or loathe them, when you finish up any crochet project you’re going to have to weave in ends. If you’re doing a smaller project that is only one color, you might only have two to weave in (beginning and end). However, if you’re doing a more complex, multi-color project and haven’t weaved in along the way, you could have many hours ahead of you.
Personally, I find weaving in ends cathartic. This step is the one where your project completely transforms and becomes usable!
