I use 100% cotton sateen fabric printed in the UK with my original batik design showing a repeating mirror image of butterflies in a meadow (inspired by a holiday in the Pyrennes). Each shade is individually made by me. Available to fit a UK/continental lamp base or ceiling light. The fabric is stuck to a PVC former to make the drum & has metal rings top & bottom. I make each lampshade to order and it is available in 3 sizes. 20cm is ideal for a small table lamp, 30cm diameter is great for a table lamp or ceiling light in a medium size room. For a large room ceiling or standard lamp I would suggest the 40cm diameter shade. Feel free to contact me for advice on sizing if you are not sure.
