yes, your drawn block of any size can be put into a block of any other size... your cutting measurements could end up very strange, though. Is your block really 6.5", or is that the unfinished size? A 6" finished to a 12" finished is the ideal resize in my estimation. You do not need to redraw the block... just change your layout block size to the larger size, choose the block and go to print your cutting sizes. HTH
