I think about a year ago I bought a sharp crochet hook.
It has been patiently waiting
to get used.
And now I finally came around to using it.
The hook has a sharp point on top
so you you can easily make edges on fabric
without hemstitching first.
I made flanel pajamapants and made a shell edging.
Read this post for how to.
Allthough it damages the fabric a little bit
I love the result.
