That was my thought as well about the snugness - I started out with a topper and I started with attaching the front first. I found at times I would put the hairline where I thought it went and would either be short in the back and have a bald space or be long and have issues with tape not sticking because it would be in my own hair. I as my original question because it seems when I start from back to the front with my full cap even that I mark in front of where I think the hair line starts and I usually have a slight amount that doesn't get glue and have to lift it and put glue their. I don't know if it is because I pull the front tight and that little extra is what is not getting glued or not.
