This week's lunchtime masterclass is with Samantha and Nicola Chapman, the sisters behind beauty blog and YouTube channel phenomenon Pixiwoo.
This chat is now closed but you can read the full transcript below.
Samantha and Nicola are in their early 30s and started working as make-up artists soon after their sixteenth birthday. They have worked constantly doing magazine lay-ups, pop promos and advertising make-up.
Two years ago they were asked to teach a friend how to do a "smoky eye" and rather than describe the steps over the phone they uploaded a video to YouTube demonstrating the look in easy-to-follow stages.
The video was a quickly a hit and has been followed by almost 300 videos to date. Pixiwoo's audience now happily migrates between their blog, Twitter feed and Facebook page as well as constantly growing on their YouTube channel,which serves five million views a month.
The sisters live in Norwich with their partners. Nicola and Ian have just had their first baby and Samantha and Danny have two little girls aged three and seven.
This masterclass has now finished but you can read all the questions posed to Sam and Nic, and their replies, below
