Yarn & string lanterns are quite popular since couple years. it's like iphone, stylish, costs is almost zero but price tag is absolutely overkill (at least in turkey). this entry shows how to do it yourself.
Step 1: Requirements
+ 50~100 meters of straw rope = $2
+ wood glue = $2
+ balloon (condom works too) = $0.5
+ 3000k warm white light bulb = $5
+ textile dye (optional) = $10
Step 2: Process
1. inflate the balloon
2. dip the rope to wood glue
3. wrap the wet rope around balloon
Step 3: Finalization
now wait about 2-3 days to dry. pop the balloon and clean leftovers from the cage structure. few people on youtube adding some water and corn starch to make glue more thinner. i didn't used it but it allows quick cleaning in this stage.
Step 4: Hang to Ceiling
I wrapped the same rope around the light bulb handler and attached the chandelier without touching to cage walls, it's the hard way but i think that's more stylish and blocks more light to watch movies on flat panel and do the basic tasks in the room same time.
my phone's light meter measured 80lux which is shows 1000 in full overcast day
original product = around $30 to 80
handmade version = $9.5 plus 2 hours total
