Compression gloves worked for me for quite some a few years, but I did eventually have to give up the craft.

I actually do origami daily, and it keeps my hands and wrists and elbows loose and flexible. When I go for days without doing origami, I get pains in my elbows and sometimes my hands. It's kind of like physical therapy for me. If I spend too much time in a row, like over 3 hours of folding, it can cause my hands to cramp a little. I just limit my time with daily folding sessions.

i love having a good stressball to squeeze every 5 minutes or so to help move my muscles before cramping happens, and also it’s important to take breaks! i do embroidery so it’s a little less wrist work but the advice should still help

❤️ rest!! Your project isn't going anywhere. I like to stretch and massage the cramping muscle and leave my work for at least an hour.

If my hand starts to cramp I usually try to massage it out a bit and take a few minutes break to gently stretch my hand, if I'm having trouble with my fingers feeling unstable I've started using a little bit of kt tape to support those joints!
