Does the sponge behind the first spool matter? I lost the first sponge and the sponge behind the spool to be loaded came out. I lost a roll of film due to the spool not winding tight.
Depending on your Holga you might need something in there to keep your film snug. If you did lose a roll of film, I'd recommend replacing the sponge or using the cardboard method explained here: http://www.squarefrog.co.uk/troubleshooting/detached-sponge.html
