| For a smock-style apron I recently made, I developed a shortcut for trimming off excess fabric on two large pattern pieces. Instead of taking the time to mark a 3/8" seamline to be completely trimmed off, I found a much quicker way to remove the unneeded seam allowance. The steps used are as follows:
1. Stitch a contrasting basting line around the pattern piece wherever you need to trim, in this case at 3/8".
2. Using a scissors or rotary cutter, cut just inside the basting line (refer to arrow in photo) in order to eliminate the unnecessary seam allowance.
3. As you trim, remove scraps of fabric and any stray thread left behind.
Basting a cutting line was much quicker than marking the seamline with a water soluable marker and then removing the excess fabric.
I hope this tip saves someone else a lot of time as it did for me.
