Hi Bubbles, I used to have hair extensions and whilst they do look lovely they are high maintenance. Its normal to feel bumpy - you just don't want your fella running his fingers through your hair! They feel very strange to sleep on t first too. I found them hard work and my hair never felt as clean as it might. Don't have them cut out as the knot is part way up your own hair and you will end up with a very short hair cut which i am guessing you wouldn't like - when they have been in a few weeks and loosened off they will slide down your hair with a little tugging and you can get them out that way if you really want to. I never noticed big gaps here and there in mine but used to have to go back for infills every few weeks. You've probably spent a lot of money on them so enjoy them whilst they are in and look after them because it is expensive to maintain them
