Here' goes: notice I use one word per piece so memo seems very long but I KNOW all the words instaed of having to make up words and then try to decipher them again.
Using Old Pochmann as described by Joel van Noorts page.
edges
speedy chef - carrot - flowers -tomato - red smurf - foodmill - vomiting - reflectorpole - bench - spaetzle maker puts buffer back (apple already in place)
10 no parity
corners
move buffer to 2nd target (D') - vomit - spaetzle maker - flowers - superman puts spanish buffer back - place buffer in 4th target (D) - apple - parrot returns spanish buffer back in place.
fix two twisted corners buffer and 1st target
So I just imagine a story with these words and I find they are quite easy to recall.
in this method the difficulty is to recall the story, not recalling what the words mean.
As mentioned before, the crazier the story the easier to remember...
What a fun scramble for corners with buffer already in place and 1st target occupied and twisted in its place
0ffcourse some of these words may be silly or meaningless to you because these are MY code words.
For example food mill, speedy chef and spaetzle maker are all items we produce at Tupperware and have a two-colorscheme.
I plan on switching to "assigned letters per sticker" in the future but first I want to get conficent in the whole BLD process.
The longer stories I have to remember now can only get easier in the future ;-)
Even with the letters you may find it usefull to work with a fixed set of words.
Take a look at Chris' list of letter / letterpairs for inspiration but words will stick better if you come up with your own.
