first take your old pyjamas.it is better to use a woolly fabric.
cut it from middle and get rid of its stitches by cutting from edges.
get two folds of fabric like this.put them over each other and adjust their edges to get a rectangular pair of fabric.
from long sides of the pair,stitch them together to get a cover just like pillow covers but a cover which has open ends.
then,stitch the edges of open ends to have a better appearence.
the most important step is making the skeleton of your lamp. to do this;
join four long wooden sticks with shorter sticks.you can do this with glue or nailing.but nailing gives better results.
at this step you can take help from your dad or boyfriend too:)
after doing the skeleton,put the cover onto the skeleton.
now there is your new funny lightning:D
after installing a light bulb(fluorescent ones are better)you can congratulate yourself:D
here it is lighted.
