THIS DOES NOT WORK!

Starting to get really tired of this now. I have read, check out videos etc etc etc how to do but I do not get it right! It looks fucked up. You can see the lace from everywhere! The hair gets stuck in the glue, I dont get the positioning of the system.
Everything looks so terribly easy at all the videos, and when you read but damn it so hard when you going to do it by yourself! This is frustrating!

Now is the 3rd time I'll try to glue it in place. And every time is so hard to get rid of all the glue that attaches to the skull! Is there any tips how to clean the scalp from glue?

I think I have to visit some who really really can do the attachment...
