She was actually really starting to get into what she was doing. So much so that she almost forgot why she was frustrated. Almost. But that little niggling bit of irritation that was tickling the back of her brain like a scratchy bit of hay sticking through a mattress in the middle of the night, that little bit was what had her swinging her hammer hard enough to make her grunt with each throw. But it was reducing her rocks to powder fairly quickly.
She was a bit sweaty from the exertion, her hair was coming undone from the braids she'd woven in that morning, and the front of her shift was now stained with dirt and bits of rock. So of course that was exactly when Loki would finally show up. Instead of dropping the hammer, spinning around and throwing herself in his arms like she wanted to, Sigyn carefully put the hammer on the boulder she'd been using as an anvil then brushed the excess dirt from the linen. When that was through, she then turned around to find him approaching.
Setting her hand on her hip, knowing full well it pulled the shift off of one shoulder as she did so, Sigyn gave him a slow once-over look. Then she grinned back at him and said, "Well then, I guess you better get stripping, since it's always you that's naked. Not that I'm complaining. But as you said, at this point, it's tradition, so... " She gestured with her hand, waving towards his body in an indication that he should start undressing.
