I know this is silly, but here goes...If I have a pattern that says it is a 10" finished block and I want to make it a 12" finished block could I just add 2" to EVERY measurement in the pattern? Would that make it come out to a 12" block? If it says an 8" block I would just add 4" to all measurements right?
This sounds logical to me but I want to hear from the experts before I mess up a bunch of fabric and waste a lot of time. Thanks.
