Notes

To begin, measure the front of your jumper from the shoulder seam to the hem and across the bust. Cut the front from your jumper up to the shoulder seam and armhole seams.

Squares are made to fit across the front of your jumper. Each Square should be ¼ of the width of the front. You can adapt the pattern for the Square by working fewer rounds, or by working additional rounds. Each dc round should add approx 1cm to the measurements and each tr round should add approx 2cm to the measurements.
