In a pinch to keep drapes tightly sealed so cracks of light don’t peek through, we use pant hangers that have the two clips on them. Overlap the two sides of the drapes together and clip them. The hangers are usually readily available in the closets. We also do this in hotel rooms. Works great. 

The light is coming in from the edges of the 2 curtains, not them not being fully pulled together.  Unfortunately, the hanger trick won’t work.
