How to Clip Seam Allowances | Clean & Professional Finishing
Clipping seam allowances is a small but important technique that makes a big difference in how curved seams behave. By releasing the tension in the right places, seams can lie flat, turn evenly, and press cleanly — for a noticeably more professional finish.
Step-by-Step Guide
-
1
Clip perpendicular to the seam line
Make small clips into the seam allowance, perpendicular to the seam line. Stop just short of the seam — never cut into the seam itself, as this can weaken it.
-
2
Clip enough to release the tension
Make enough clips so that the seam can open up and lie flat when turned. It’s better to make several small clips than too few — especially on tight curves, where the fabric needs more room to move.

3
Use the right part of the scissors
For precise clips in tight areas, use the tip of the scissors, or the inner part of the blade for a more comfortable grip on longer sections. Just use whatever feels most controllable and accurate.
Pro Tip
Always use sharp scissors and work slowly — dull blades make clean clips much harder and increase the risk of accidentally cutting through the seam. Precise clips make a considerable difference in how evenly curved seams turn and press — so take the time you need.
