I've done paper-piecing off and on for years and each time I try another block, its time consuming. For me its the backwards thing that throws me off. I persevere and after a few pieces I'm in the swing again.
Cut your fabric pieces about an inch larger all around to be sure you don't get short on an outside edge. A little waste is better than doing it over.
Just remember, its a given. It takes longer than a regular pieced block but its usually very beautiful when finished so worth the extra effort.
