two questions about SW, and one about ASL & call to writers

[Kimberley A. Shaw]

Hello Val and everyone:
am coming up with nitpicky nitty-gritty questions about SW, now that I'm
starting to type in whole texts!
So, question #1: what is the best way to show one hand going *behind* the
other one? For example, the signs for "sunrise"/"sunset" in the ASL
SignPuddle: the right hand is the sun, approaching and then going above
the horizon of the left hand ... put one arrow? two arrows, one
above/below the horizon hand? 
Question #2: A phrase begins with a two-handed sign, and then one hand
continues making that sign while the other one is making a new sign (or
two). For example, both hands establish a wall, and then the left hand
continues being a wall while the right hand becomes a person looking over
that wall. Is there a special "tie" symbol for that, and where is it
located?
Question #3: for the more-fluent ASL speakers -- I figure that putting an
eyebrow-raised face at the beginning of a sentence will be the best way to
establish it right away as a question ... but what would be the right
thing to call it in SignPuddle? I would like to have a dictionary entry
for this kind of marker, as I use the "e-mail" and "translate" features
*very* heavily for creating SW texts and would definitely be using an
entry like this quite a bit.
There will be several more new words hitting SignPuddle ASL, as I am now
typing in a version of "Star-spangled banner" (based on Lou Fant) for my
ASL reader ... can you tell 4h of July is imminent? Again, I want your ASL
SW-stories! I have Donald Baer's NAD story, Paulette Sottak's Denmark
trip, Gabriel Tollette's Runaway, and Charles Butler's Stars-spangled
banner (shame that only 1/2 of Kevin Clark's Gallaudet story is in SW).
But I do want more ASL stories/writers!
Best,
Kim from Boston
