Clipping and Trimming Seams

Eliminate bulky seam allowances and help garment sections lie smoothly


Eliminate bulky seam allowances by clipping and trimming seams in specific areas of a garment. Watch as garment sewing expert Judith Neukam demonstrates her recommended method. She says the tips in this video “will help you make beautiful garments with smooth seams and no lumpy corners, ripply curves, or bulging hems.”

Judith shows the correct method for clipping convex and concave curves on princess seams. She shares a seam pressing tip once the princess seam clipping is complete.

Also find out how to trim or clip bulky seam allowances on outside corners, as on a cuff or waistband.

Trimming eliminates bulk under the arms on set-in sleeves and between the legs in the curved center seam on pants, too.

Seam bulk can even be reduced in hem allowances, as Judith demonstrates.

This video on clipping and trimming seams is part of the five-season Teach Yourself to Sew series.
