Do you ever make tassels? Back when I was playing with book bag prototypes, just on a whim I made a tassel for one of them:
It’s attached to the top of the side seam, so it’s not really a bag charm.
I made it with yarns that match the fabric colors, with fuchsia on the outside and pale yellow and two different greens on the inside.
I still like how the other shades peek through the hot pink. I’m just not sure how practical it is. Thoughts?
