Okay, step two is getting the sigil to follow back onto -this- wall from the sheet.
>Frown. "...I think I'll have to get it to move back onto the wall from the sheet. But, that shouldn't be problematic. It doesn't move if you're watching it, though, so close your eyes for a moment, alright dearie?"
>Move a short distance away from the wall-sigil to some clear wall space, assuming there's some to be found, and press the sigil-side of the sheet against it, closing our eyes. Then, with our other hand, try to drag it back out with the same method we used to try to get it on the sheet in the first place.
>Open eyes, remove sheet, view results.
