Preparation

Sewing
· move darning ring smoothly
· work from left to right
· move without using pressure
Method
· sew first row
· turn work by 90°
· sew over the first row – not too close for a soft finish
· turn work by 90° again
· complete darning loosely and in same direction as first
row
· in tubular items
first step in a horizontal direction
second and third steps in lengthways direction
· when you have mastered the technique
work the rows in irregular lengths so that the ends are
lost in the fabric
Important
· change direction in curves (no points)
= prevents holes
= prevents thread breakage
· move as if writing L or M
· do not sew in circles = these do not mimic fabric
