I've not heard of this but maybe you're all already doing this and I'm slow. I just bought a Rae Morris book and she recommended putting mascara on using a lash comb rather that mascara brush. Thought I'd give it a go and it's ace! You can get full dense coverage but it's feathery and light. I just used my normal Max factor mascara and a metal Lash comb. Smeared a ton of mascara all over the spikes and just combed it through a few times. Just thought I'd share. I'll be doing it that way from now on
