Light Cracks!!

I'm having and issue now. I need someone to suggest some things I could do to fill light cracks in my desk so that no light is being revealed.. It's pretty obvious at this point and I need it to be fixed so where I can open it whenever needed.

Please list some household items that I could use, thanks.

At the hardware store they sell foam tape, it works well for sealing cracks, it comes in different widths with adhesive on the back. Works well for doors and such, I think that is what it is made for is doors and windows.

Seal the cracks... Not much we can say, you're the one with the stuff, use a blanket if you have too.

I had the same problem

You could try using some sort of caulking meant for sealing kitchen sinks or bathtubs.
I tried this method, but with the wrong kind of caulking. it turned out quite messy.
Just an idea.
