I'm working on Steves floral clock pattern. I've done all my cuts but I'm wondering how you would access the back of the clock mechanism in order to change the time or battery once it's in place. The clock is a pressure fit and as far as I know it is supposed to be pretty snug. If I simply glue the backer on, then it can't be accessed from the back. Will it be easy enough to pull it back out from the front? I figured the snug fit would make it difficult to pull it out from the front. Any suggestions? This is the first clock I've ever done so I'm almost certain this question is just my inexperience and has nothing to do with Steves Palm.
