Once you’ve settled on the layout, heat up your glue gun. Start gluing the bench down first, then the bodies. Go slow, because hot glue dries fast and you don’t want your figures to look like they’re doing some awkward dance!
Oh, and pro tip: don’t touch the glue right away! I thought I could fix a stone that shifted and ended up burning my finger. Ouch. And that isn't the first time...Let it set before trying to adjust anything.
