Yeah, for most thinner things, the tool isn't necessary. For my loom knit plushies I do kind of need it just because I don't have the finger strength to get the backs fully on. They always click like they're on but they're not fully snapped down past the first ridge and end up popping off. So it's nice to be able to apply my full weight to it to squish the yarn down and pop the back on properly.
