Weaving ends in felted bag

How important is it to weave in the ends for a felted bag? I just did one and there are some annoying puffs that appeared which could be from ends poorly woven, but then again I can just cut them out right?
Thanks for the help! I did stripes and there are so many ends…

I would weave them in a little just so things stay together well when you put it in the washer. Not necessary to be perfect though…the little ends left will either felt into the bag or can be cut off when you’re finished.
