Ithink it does get easier as you go.
Some patterns will have the measurements of the pieces of fabric to cut figured out, some have the 1/4 inch added on and some don't. I use cardstock or and old envelope for the folded edge and my 1/4 in ruler.
To me the hardest part is the really pointed deep angles getting the measurements of them figured correctly the first time. I also have to agree practice, practice, practice. I love paperpiecing.
When I do multiple blocks I chain sew and do at least half or more at a time.
