Fabrics & Best Seam Finishes

Batik: Flat fell seam or sew with a plain seam and serge together
Batting: Butt the raw edges together and hand overcast with basting thread to get the width you need.
Beaded Fabric: Finish with a product like Great Seams as in Hong Kong finish. Eliminate facings. Finish the neck and armholes with bias silk charmeuse or line your garment, making the attachment at the neck and shoulders.
Boiled Wool: Sew seams and clip curves. Press seams open and top-stitch on each side from the right side using a wide double needle or top-stitch each side separately from 1/8” to 1/4” allowance from the seam. Trim to your top-stitching.
Brocade: Press seams open and overlock separately, even if lined. Use a Hong Kong finish with lightweight silk or bind separately with double fold bias.
Burnout: Finish with a narrow French seam.
Charmeuse: Use flat fell or French seam on serger.
Chiffon: Use a narrow French seam. On long vertical seams, sew with tiny zig-zag stitches to prevent drawing up.
Corduroy: Serge seams separately or flat fell the seams.
Crinkle: Sew with a tiny zig-zag.
Damask: Sew flat fell seams.
Denim: Sew a straight seam. Serge one seam allowance and trim the other without turning under. Overlap the serger seam allowance onto trimmed seam allowance and topstitch. This forms a fake flat fell seam that is less bulky.
