Thanks to all for the big 'thrift' debate yesterday.  I have no access to the correct answers, I just believe what I read here:

Let's hope this clue has a simple explanation:
"Sticky end for Moth and her 'Dream' friend" = cobweb.
And this one:
"Clerk provides stopgap after student leaves" = filer.  Taking the L (student) out leaves Fier.  I don't get it...
Many thanks.
