Turning Fabric Corners Without Pushing Through Them

Eight Needles Journal · Punching & finishing

A turned corner needs its fabric arranged carefully from the inside. A sharply pointed tool can push through the seam, so choose a tool and method intended for turning or shaping the particular construction.

Prepare the seam first

Follow the pattern's instructions for trimming or grading the allowance. A bulky corner cannot always be improved by pushing harder. Keep enough allowance to protect the seam, and practise unfamiliar trimming on a sample.

Shape gradually

Turn the piece and ease the corner into position with a suitable blunt tool. Work gently rather than forcing the point to match a sharp paper outline. The fabric's thickness and seam structure influence the shape it can form.

Inspect before pressing

Check that the seam is intact and the corner is evenly arranged. Press only using the fabric's appropriate method and temperature. If the result remains bulky, review the construction rather than introducing a sharper tool into the corner.

A practical example

A turned corner remains bulky. Reopen the sample and review the seam-allowance preparation prescribed by the pattern. A sharper point or stronger push may create a hole without solving the underlying bulk.
