Finishing up a beanie

So when the pattern says to thread tail through remaining stitches, pull tight and weave in ends…That’s all I have to do to secure it? it’s not going to get loose and fall out?

Sorry, I’m just worried…

It should stay just fine.

I did exactly this, but why does my beanie look as if it has a scar (too bulky stitches). What went wrong?:knitting:

It could be the thickness of the yarn, or you did it with too many stitches.
