Been looking at a lot of the humidor threads on here and doing some other research online and I still have one question left. I see that the recommendation is to use Spanish cedar to line the box. However, how thick do you make the SC and how do you affix it to the I side of the box? I am a little fearsome of using glue for fear that it could somehow ruin the cigars over time. I don't smoke but I'd be making this for my father-in-law who is a huge cigar smoker, thinking it'll either be a Christmas gift or maybe if I could get it done by September I'll stock it with some good smokes and give it to him when his newest grand baby arrives!
