Hi Hun. There's a fab website by Rachel bridges. You do have to pay a one off payment to join but it's been like a bible for me. Here's the link

I did a day course with marvel lash when I started and must admit I redid my training with Flirties. What lash lengths and thickness did you use Hun? And def tint them
will help you loads to see the lashes.
I use 0.15 thickness lashes. I use B curl for my elderly ladies or those wanting a very natural look. Then C curl on most of my clients who want them a bit more noticeable.
I always have some 0.12 lashes going too and apply these to more finer baby lashes as the 0.15 can be a little bit too heavy.
Another tip is make sure you don't load too much glue on your lash extension. Gently dip a few mm in and slowly pull it out so there's not a blob on the end. And don't swipe the lash extension on the natural Lash, simply place it about a mm from the base.
I was trained to use a lash map, did they show you that?
Hope that helps Hun. I started my training last jan and this year did volume. Stick with it you'll get there
