A girl on youtube was describing putting the mascara brush onto the lash then jiggling (I can't think of the right word) the brush back and forth so that it lightly tugs on the lashes For me, this means I only have to get the brush to my lash I don't also have to keep it steady while brushing.
I tried putting mascara on a lash curler and then curling the lash, as various people were describing on youtube. It did transfer to the lash, but at the time, I thought the process had somehow broken part of my lashes off (made them shorter).... later, I decided that didn't happen, but it keeps me a little worried about the process.
Anyway, the idea of putting the mascara on a surface and pressing it against the lash is something I want to experiment with.
Also, I think it is working to put petroleum jelly on the lashes with nothing else as a way to make lashes grow... maybe. I use a mascara brush (I bought a pack of 100) and apply it like mascara. That, you really don't want to go into your eye though... Longer lashes would make it easier to apply mascara, as someone was saying above.
