my notes have disappeared ?????????

last year i staerted a vest , made up some pattern and this was my
carry around project , put it aside during the summer , finished the
half bodice of back 2 1/2 frons ,,,, and my calculations are`n t to be
found ,,, Weird i usually write it all in a copybook , but somehow not
this pattern,,, it was `born`, while riding the train , thus had it on
loose pages ,,,,, and now ????? nada ,,,,
thus i ended up yesterday counting stitiches and rows and measuring
and calculating it all anew ,,,,, brrrrr
