The lamp shade is made up of three section; two of which are textile and the third is a wire feature that will separate the two.
The textile i had selected is a grey weave fabric, perfect for implicating an industrial-esque aesthetic, and will bring out the grey tones within the walnut legs. However, the length of the fabric roll was only 1 m 40 cm, and the circumference of a 50 cm diameter circle was 1571.07 cm – exceeding the maximum length of available fabric.
Therefore this measurement was halved, and tolerance added (lengthwise) to allow two pieces of fabric to attach, a join in the middle. The fabric is quite a loose weave and frays a lot, very easily, therefore i tacked the edges in a quick hem, this was later unpicked and burned to stop the fraying,
The fabric, once joined into one long strip was ironed and laid out on a table. A piece of sticky-back PVC was placed on top and stuck along its edges with masking tape to hold it in line, straight, with the weave. Once i was happy with the placement, the masking tape was gradually removed in time with the backing. The backing peeled off and the sticky side of the PVC was smoothed down on to the fabric, the backing was pushed under the rest of the PVC laid out to improve the accuracy of the application.
On one side of the PVC piece (vertically) a piece of industrial strength double sided tape was applied – this will be hidden by the overlap and hold the shade together. Approx 1 cm of the PVC was removed from both the top and bottom horizontal edges (therefore reducing the vertical height to 20 cm) to allow the fabric to wrap around and cover the rings.
The rings were covered in the same double sided tape all the way around. A small section was peeled off both rings, and these were lined up parallel on the edge of the PVC. The rings were then rolled along the edge of the PVC, removing the sticky tape as you went until the drum shade form was complete.
The 1 cm of fabric tolerance was then wrapped around the lamp ring and tucked between the ring and the shade, hiding the ring and creating a nice clean edge on the outside, and inside of the shade.
