Nichrome is what I use. I’ve bought it in long rolls so I can cut to size and also pre-cut like these: 200 Pieces High Temperature Nichrome Wire Jump Rings, 21 Gauge with a Plastic Storage Box, U Hanger Hooks for Hobbyists DIY Pendant, Ceramic Ornaments, Fusing in Glass https://www.amazon.com/dp/B081SFJ66D/ref=cm_sw_r_cp_api_glt_fabc_1V1E3ZS1E1TBV0TTT6ZG?_encoding=UTF8&psc=1
Nichrome wire. You can get a small spool from your local distributor or these little doodads from Amazon:

I've personally worked with the above and had no problem. It would be cheaper to just buy a spool, though.
