I love the idea of keeping my work surface clean as I work. Heck, anything that helps me be clean I love! I recently built myself a large L shaped desk, and in the corner section that I designed to scrap in, I drilled my garbage hole!
Cardboard is the only filler between hollow core dores, so I moved the pieces in my way, dry fit the piece of wood, and took it out again. I put glue in the hollow door and onto the wood, slid it into place, and clamped it down. I also used masking tape to make sure it stuck and stayed right where I wanted it.
When the glue was dry, I removed the clapms and tape and proceded to finish my desk by painting and varnishing it.
On my new desk, where I make jewelry, I don't need a large garbage can because scraps from jewelry making are so small. So my solution here is to just put a cute bowl on my desk top to act as garbage can, and this I just empty on occasion. ;)
(Look at that cute metal bowl on the right of my red bowl. I should have included it better in the photo here. I use it to keep my jewelry tools in, and because of all of the circles, I can hang earrings on it as I make them. he he.)
