Idea for you about the mixers being so heavy and unweildy.
Put the mixer on a folded towel on the table top and put the container you want to fill on a lower surface right next to the table and tip the bowl over carefully to get the contents to respond to gravity. With icing you gotta coax it out--but the bowl lays down better. With cake batter you get used to the 'flow' after a few times.
Y'know the storage containers you have under the table? Would those work? To set the cake pan (or whatever) onto???
Just a thought for you--that's what I always did. Even the big 40/60 quarts come on the little round dollies on wheels--you just learn to tip them over into a waiting recepticle, cake pan, whatever.
You place is wonderful!!!!
