I'm looking into building a small wall hung jewelry cabinet, from what i have seen most of the doors are panels. now my issue with this is that I'm building it in Colorado and then it is being sent to Nebraska which is a big change in humidity and im concerned that the panel will expand itself apart. So I'm Looking for thought on Either how to prevent this or a design that doesnt have panels. this will be one of my first medium sized projects so i dont have a huge amount of experience with these things so i appreciate any thoughts.

Im actually changing the wood to be hickory on the bottom (instead of mahogany), because i have a lot of hickory laying around, then the top will be Purpleheart because my friend is a big fan of purple., the issue with that is i have too resaw the purple heart down as i can only get it in 4/4 stock, and i have to do this on a table saw so i need to get some more tools to get it to come out right. and I believe I used way to much glue on the previous attempt.

thanks will do i made so many mistakes on that piece it was good to do it, so i know i need to cut all the Miters before glueing anything, as i didn't so had to fix the big holes, also learned while walnut is beautiful glue just soaks right into the grain ruining the finish.

The issue with the rubber band method is that the lid only has 3 sides, but I did use that method for the base I think that the tape method might work though.

Hi guys this is my first post and I'm having some difficulty, I'm making a small box designed for cards. I made a prototype since this is for a friend, and i found a few issues, but my main problem is getting the top correct, it is 3 sides due to the angle of the lid all mitered together but everything slip and slide so getting a nice tight joint just isn't happening. I really have no idea how to put decent pressure on the joint without it slipping apart ?
