I've done that too, that style takes waaay longer and ends up with thinner looking tails.
yea i've switched to hot gluing the fluffs lol
You won't get a great result doing that. Sew them on instead.I've gotten a great result so far
I would never do it. It's lazy and your overall quality will be poor. If it's a time saving technique for a personal project then it's fine, but never, ever, ever sell a yarn tail who's floofs have been glued to the core.
