Ahhhh! I see!
It's so funny that there are all these terms out there and none of them were used when I took my course. It makes me feel silly! But, I know what you are explaining....mine were awful when I first started (finished in April). Now, I no longer see the line and I'm getting better at not having any lifting at the cuticle. I'm still having problems when appling my tips and getting them to fit perfectly. I sometimes have them start to lift at the sidewalls. I think I customize them to much on the sides and then they aren't big enough.....keep practicing...I know!
Thanks for your help and listening to me rant!!
