If you're attempting one of those little fire demon charms for the first time, here's what I wish I'd known before starting mine. Circular beadwork looks simple on paper but the first two rounds are where everyone gives up. Use something stiff like FireLine or even doubled regular thread, because flimsy thread makes the center flower pucker and the whole shape goes wonky. Work the center in bright yellow, then count your beads on every single increase round. I skipped counting once and by the orange ring mine looked more like a fried egg than a flame. Keep the gradient going as you work outward, yellow, orange, then the deep red for the outer spikes. The spiky edge is where patience matters most. Add three or so beads at a time on the points, and don't yank the thread tight or the tips will curl inward. Take your time on those, they're tedious but they sell the whole flame look.
For the eyes, stitch on two black beads after everything else is done, not before. I tried placing them mid-build and kept snagging my thread on them. Then loop a jump ring through whatever top bead looks solid and attach your clip. Mine survived a week on my keys already, so it holds up better than you'd think.
