Make the Interior Come Alive
To pull off the look of India in your classroom, you need dramatic color. One of the best ways to achieve this is with tulle. Purchase it in vibrant colors of red, orange, blue, green, gold, brown, and more. You will need to be able to think outside the box to achieve this look.
Start by attaching one end of a bolt of tulle to the ceiling in a corner, then drape the fabric down and then back up to the middle point. Continue with different colors, from each corner and then gradually fill in as much or as little as you wish to, forming a canopy overhead. At a minimum, have all four corners tufted with fabric, swagger down and cinched back up in the middle. You can also attach light weight objects with string or wire to the frame without damaging anything. Keep the swags high enough that the tallest student can't reach them easily.
The reason you need to use tulle, is because of the lighting issue. The light can effectively stream through this see-through material, yet still cast a slight shadow of light in the color of the fabric. If you leave the rest of the ceiling open, then the bright lighting will be able to come down to the students. If you wish to totally fill the ceiling in, It would be awesome, and dramatic. You can supplement extra lighting with lamps.
Next, you need to think about the floor. Think about opening up the center of the room to an open floor space. Place all the tables or desks around the room facing the center, but along the walls. In the middle of the room place a rug that makes you think of India. If you have a rug from India, this would be perfect.
Most Indian rugs are brightly colored, but some are more neutral as well. Whatever you can find that would make you and your students get the feeling of India would be perfect. You can also use many rugs to make a completely covered central carpet in the room.
Now it is time to place some pillows if possible. This will totally bring the students into the feeling of being in India. During the lecture part of the lessons, your students could sit on the carpets either on pillows or inside a circle of pillows you place on the floor.
With the ceiling and floors feeling more and more like India, now it is time for accessories.
