I shaped by beads by hand, then used a cocktail stick to make the holes in the beads. I also added ribbed detail to the triangles by pressing down with the side of the cocktail stick. I baked them at 110 degrees for 30 mins on a piece of baking parchment, then allowed to cool. For the triangle necklace I plaited 1mm leather string and wove the beads in, I used an existing silver chain for the balls.
I noticed my hands got glittery very quickly when using the metallic fimo, this did transfer a bit to the other pieces but I quite liked the effect.
