Darning Holes or Worn Areas

Replaces both lengthways and crossways

threads in all fabrics.

Preparation

• stretch fabric into darning hoop (optional

accessory) to prevent distortion

• use the slide-on table

Sewing

• move the darning hoop smoothly by

hand

• work from left to right without using

pressure

• when changing direction on top and on

bottom, move in curves (avoid points as

this prevents holes and thread breakage)

•work in different lengths so that the

thread is better spread over the fabric

Poor stitch formation

• if the thread is lying on the

right side of the fabric, the

hoop is being moved too

quickly

• if there are knots on the wrong

side of the fabric, the hoop is

being moved too slowly

Thread breaks

• if thread breakage is a

problem, it could be that the

hoop is not being moved

smoothly

1. Stitch Over the Hole

• sew the first rows to cover the hole (not

too close, sewing beyond the worn area)

• work the rows in irregular lengths

• turn work by a quarter turn - 90°

2. Cover the First Rows

•sew over the first rows - not too close for

a soft finish

• turn work by a half turn - 180°

3. Complete Darning

• sew loosely and in same direction as 2nd

rows
