Useful - other people drafting basic block from measurements- yay. No time to thoroughly read through the steps yet, and I am not sure if all the 'rules-of'thumb' allowances (e.g. the "add 0.5 cm here and there"-why?) are explained, or if there is a distinction made btw front and back measurements e.g. bust - are front bust measurements used for front block and back chest measurements use for back block (hip, too?). But definitely useful.
