Buy a black base and cord here for $6.80 a piece. It looks like the above pendant has about 75 lights so you'd be spending $510 on just the cords and bases if you chose this option. You can also get it in white.
You could choose a different cord and base for much less. This black cord and porcelain white base is only $3.15 a piece. Also in all white.
I also thought this one was interesting. It is $7.36.
Tie the cords at the top with a few plastic tie cords. Then connect the ends of the cords with those grey things that look like lego pieces. I believe they are electrical relays. Then use these 11-watt bulbs for $0.86 a piece that would be $64.50 for 75 bulbs. There's also a 7.5-watt bulb here. And here's a 15-watt bulb. I would personally go for the 11-watt. You must know what your amp load is on the circuit you will be using. Most are 15 amps which will take about 1,500 watts total but I wouldn't try and max it out.
If you used the cheaper cord the total cost of the chandelier with the cords, bases and bulbs would be about $300.
Now, if you wanted a cloth covered cord you can easily DIY that too. Just buy the black porcelain base separately for $1.95 and attach to the cloth cord. I thought about maybe trying this for Henri's room since he has a high ceiling. The main color scheme in his room is orange. So I liked this cord option. Only $0.60/ft.
I also liked the red and white or black and white striped cords. They ranged in price from
braided red stripe $0.60/ft
braded black stripe $0.60/ft
red cord stripe $1.18/ft
black cord stripe $1.18/ft
They have many more colors and patterns. To see all of them check them out through this link.
