Congrats on your developing! It's a fun adventure you're starting.
I share your frustration. The first time I tried to do home B&W developing, I was fumbling around in the dark with a cheap, poorly-designed plastic reel and a curly roll of 120 film. I wrestled with the film & reel ... it was so hard to tell what I was doing. I think it took me 20 minutes to get the stupid thing on the roll.
When I turned on the light, I was horrified: I had loaded the paper backing on the reel -- the 120 film itself was in a pile on the floor! After the shock, I had to laugh about the whole thing.
