I have done it! It worked out great! Gaffers tape or foil with a black back will be your best friend. If you have spent much time shooting a holga you already have a few rolls of gaffers tape laying around so just tape up the hole and insert your film and tape up the body and you are good to go. 3 full turns to start the film and 1 full turn to advance the smallest mask sized frame. Want more fun? Shoot it with 35mm! Enjoy!!!
