1. Cut three lengthwise pieces from one width of fabric, one piece for each side and one for the foot of the bed. Each side piece, cut width of each piece equal to the length of the base plus 59.8cm. This allows for pleating, seam allowance, and hem allowance. For double or queen, cut one piece for the foot of the bed, with the cut width equal to the width of the base plus 48.5cm.
2. Place the fitted sheet over the base. Using non-permanent marker, mark sheet along upper edge of base on each side and at foot of bed, Mark corners at centre of curve. Mark centres at side and foot sections.
4. Position bed skirt so centre of fabric is placed at centre of foot. Fold pleats in place at markings as shown, with 7.5cm on each side of pleat; pin to base with seam allowance extending above upper edge. Seams will be hidden in pleats.
5. Remove bed skirt from base, repositioning pins to secure pleats. Press pleats in place, with even pleat depth from upper to lower edge. Machine-baste 1.3cm from upper edge, securing pleats.
6. Lay skirt right side down on top of base. Pin upper edge of bed skirt to fitted sheet, extending 1.3cm seam allowance beyond marked line.
7. Remove bed skirt and fitted sheet from base. Stitch bed skirt to sheet, stitching 1.3cm from raw edge; finish seam allowance.
