If you haven’t already tried it, Urban Decay do a great heavy glitter eyeliner that can be used to produce a thin glittery line or a heavy bold look around the whole eye. Urban Decay Heavy Metal has a cult following and it’s a better product than its MAC equivalent. It’s a dense glitter which is suspended in a clear gel so you don’t end up with glitter everywhere. Because of the precision of the brush and the ability to produce a fine line if needed, the glitter can be used as a daytime look as well. You can find it at various places but ASOS sell it online (I recommend the Spandex shade).
