Long story short(ish): I had been wanting to learn how to use makeup to look a bit smarter/more polished, husband bought me a MAC voucher for Christmas so I could have one of those makeup lessons that you redeemed against products. First booking didn’t work, second booking, lockdown. Now that it’s not looking likely that they will be offering the lessons anytime soon, I was wondering if the time has come for me to spend that voucher... could anyone help me with what products I should buy please? What are your best MAC purchases? And what to avoid? Currently the only products I have from them are a couple of lipsticks (Ruby Woo and Tweedy Me) and a lipgloss and all my other makeup came from Boots. 
Bonus points if anyone can recommend a YouTube channel to help me learn how to use makeup too. 
Thank you!
