Taking Time To Develop Film

I had taken my camera to Newcastle for a change of scene for my street photography prints. When it came to developing the film I rushed putting the film onto the reel in the loading bay. I think the reel had come apart in the middle so instead of the film being separated allowing the chemicals to flow over all the film, with mine the film must have come into contact with another part of the film, making them stick together so the chemicals didn't get chance to work on certain parts of the film. I did a contact sheet anyway but it was very white and only a few worked. So next time when I develop a film i will take more care and time on what I am doing.
