One of the things I got into was Paracord bracelets. They're fun to make, some can be more challenging than others, and while you're trying to figure out those knots, you are not thinking about the knots in your head!... ;-)
If you are into Essential Oils, paracord bracelets can be used as "diffusers". Basically you just add 1 or 2 drops on the bracelet (on the outside, not the side that touches the skin) and you can smell it all day as needed.
If you find paracord too bulky or masculine, you can try adding beads to your knotting, or use the same knotting technique with leather or suede cords.
To add diversity you can use metal loops and clasps instead of the more traditional plastic buckles. Just keep in mind that this will add a little bulk but also quite some weigth...
If you're not into bracelets there are tutorials for all kind of things on youtube...
This one is the snake knot, it is used in China to bring Good Luck (in this case to whoever makes the bracelet and whomever you give it to...)
You can find paracord and buckles at Walmart, craft stores like Joann's and Michaels, or on Amazon
Below are my 2 favorite Youtube channels for paracord tutorials:
