I also knit and nålbind. When I first wanted to learn nålbinding, I couldn't find a needle for it at any local yarn shop so I made my own. I was attending violin making school at the time and had access to wood scraps and a woodworking shop. After that I started making lots of needles out of various kinds of wood and even some really fancy colored acrylic ones (using acrylic blocks sold as pen blanks for turning). All told, I think I made more needles than mittens, lol. The green mitten in the picture was my first, and the needle shown "in action" was my first needle. Nålbinding makes a very thick, warm fabric. Later I also made a couple drop spindles (the one pictured is spalted pecan wood) and dyed some roving that I spun into single-ply yarn with the correct twist for nålbinding.
After violin making school I got a job driving a school bus, and one day spun some yarn as the kids were loading onto the bus to go home. The elementary kids were utterly fascinated, the middle schoolers were moderately interested, and the high schoolers pretended not to be, lol. The elementary kids all wanted a pinch of wool to take home.
While I was working as a bus driver, I got a second job at the woodworking supplies store I frequented because I figured if I was spending all my available time and money there, I should be paid for it. I had a knitted drawstring bag I kept in my pocket at that job with various kinds of wooden and acrylic nålbinding needles that I'd show to customers to demonstrate the finish that could be achieved with a particular polishing abrasive we sold. I sold a lot of that abrasive. I also sold a lot of those needles out of my pocket, and sent people to the local yarn shop for nålbinding lessons when they bought needles from me. Then the yarn shop bought a bunch of needles from me, too.
I am also a PC gamer, if that can be called a hobby. I built my own gaming computer.
I also do a little gardening. There is a strip of "grass" between my house and my neighbor's that never would grow proper grass, always weeds. So I pulled out the weeds, put down weed blocking fabric and mulch, and put big planters spaced out along the strip. I have an olive tree, some flowers that my grandfather planted for my grandmother at their house (which we dug up and kept after my grandparents both passed away and the house was sold), jasmine, honeysuckle, hibiscus, and lots and lots of aloe vera. The aloe vera propagate so quickly that several times I've had to tip out the pots and transplant all the babies into plastic cups of dirt which I gave away at work. I did have two kinds of lavender but they both died, unfortunately.
Lately I've also been making lots of lotion sticks. I mean lots. I've been making them for myself and family for maybe 8 or 9 years, but a coworker one day saw me using one on my hands and asked what I was doing. I told her it helped my hands not itch from the gloves (at my current job we have to wear nitrile gloves 10 hours a day). She said she needed something for that, since the gloves made her hands itch, too. So I gave her a couple samples, she ordered more, and everyone else got curious when they saw me giving it to her and wanted some too. I've sold lip balms to coworkers as well.
I have made candles off and on since shortly after high school. Back then I used paraffin, now I use soy wax.
I have also recently started making syndet shampoo bars and conditioner bars. I think I finally have a recipe that makes shampoo bars that harden properly. I've been using failed shampoo as body wash just to use it up, lol. So far I have made one batch of a sprayable leave-in conditioner that one of my sisters and I are testing (we have the same hair type).
I have also made laundry detergent (liquid detergent, not the soap some people use for laundry). Soon I am going to experiment with making a window/hard surface cleaner, and probably air freshener/linen spray.
I also do calligraphy, which I taught myself when I was around 8 or 9 years old. My parents gave me one of those Sheaffer fountain pen kits with the ink cartridges and different nibs and a booklet that taught how to use the pen. When I was older I taught myself more complicated techniques and have done several jobs addressing envelopes for wedding invitations. I did all the calligraphy for my own wedding invitations. I can even do Copperplate reasonably well but I'm a bit rusty as I don't practice much anymore.
I also do a little sewing but it's strictly on an as-needed basis. I made my knitting bag, and I make my own pajama bottoms out of flat sheets bought on clearance, using an old pair of very comfortable, very worn-out pajamas as the pattern. I also made all the curtains in my house.
I guess that's it. I do seem to rotate hobbies so I'm not doing all these at once.
. The filling is based on crushed pumpkin seeds and tarragon, that's where the colour comes from.
Glad it passed the test! Yes, I know well why walnut potica is so popular. But I also love tarragon, and since I had no Slovenian around here to prevent me from a recipe cross-over, I did it. The pumpkin seeds came into play since I have them at hand (but no walnuts), and
