Don't waste your time carefully cutting out each individual piece of a pattern from large paper sheets, only to cut around all the pieces again after they are on the fabric. Simply rough cut around the pattern pieces - no need to be neat. Secure the pattern on the fabric, ensuring that each pattern piece has the grainline parallel to the fabric selvedge. Then, cut both the pattern and the fabric at the same time.
