Update: realized I was bagging and boarding wrong for 15 years
I was at a shop in Denver chatting with the owner, Marcus, and he watched me handle a key issue of Saga and stopped me cold. Turns out I'd been putting the board behind the book the whole time instead of in front, which is why my older issues kept getting spine ticks in the box. Fifteen years of collecting and I just did it out of habit without thinking. Has anyone else had a dumb handling habit like that?
