To get the size right, cut a strip of paper, in the width that you would like your cuff and fold it around your wrist, cutting to the right length.
Using the template as a guide, cut a piece of black fabric, measuring double the height of the template, with an inch allowance at either side.
Fold the fabric in half, height ways, and pin along the top edge and bottom edges, so that you get a nice neat rectangle.
Sew along the open edge, removing the pins as you go.
Remove the pins from the other edge and fold inside out. Place a row of pins about 1/2 cm in from both edges.
Sew along both sides, removing the pins as you go.
Cut a strip of tartan, measuring half the height of the template, and two strips of lace to the same length as the cuff.
Pin the tartan down the middle of the cuff and the lace to either edge.
Sew along either edge of the tartan with a zigzag stitch, this will help the fabric not to fray too much, but still enough to look cool.
Hammer in two parts of a popper button to either side of the cuff, making sure that the placement is perfect for the cuff to fit nicely. Neatly stitch up the two open edges.
Embellish however you like - you could glue star studs along the cuff, or stitch on buttons and beads.
All done, wear with pride!
