The sewers are tested on the three core fabrics in a dressmaker's cupboard: cotton, wool and silk. The surprise Pattern Challenge tasks the sewers with making a simple tunic top out of straightforward cotton.

Claudia Winkleman welcomes the nine home sewers back to the sewing room to face three more challenges - all to do with testing their ability to match and combine patterned fabric.

The eight amateur sewers prepare to do battle again in three challenges designed this week to test their ability to handle stretchy fabric. They come up with some ingenious alterations from a toddler's leotard to an asymmetric mini dress.
