Dealing with creativity block

Creativity appears to have moved to Moscow.  Usually the recommendation is to just do something.  Doesn't matter what, as long as you're playing with fibre in some way.  Been playing for about 2 weeks now, and still haven't found what I'm looking for, but I know that this time of year is notorious for giving people the "blues".

This morning I played with orphan blocks for awhile, then started going through my painted and dyed fabric that lives in shelves in my storeroom.  I found three large pieces of dyed fabric that called to me, but didn't really give me any hints about where they wanted to go.  They are all a good size--about 60" wide, and about 3 feet wide.  I'm looking for suggestions.

No. 1  Here I ten to think of looking up into a forest canopy.  I think the piece would have to be cut down significantly but that might give me enough fabric to back it.

No. 2  this piece is larger but a chunk has been taken out of the other side.  At this point I have absolutely no idea how to approach it.

Piece three makes me think of skies and clouds, but maybe needs to be muted a bit  to be used like that.

There are two smaller pieces.  These are dyed cotton Damask napkins.
Again my first thought is to use them as a background, but I would want to keep the soft, gentle atmosphere.  Not sure how to proceed.  Any suggestions, Can anyone give me a sense of direction on any of these?

I plan to link this with The Needle and Thread Network, and maybe Nina-Marie Sayre's Off the Wall Friday.
