I want to turn 2 dresser drawers into a kitchen cart
Here are some ideas https://www.pinterest.com/butcherblockco/kitchen-carts/
I would put them back-to-back, attach them, and give them a single piece (wood, granite, etc) for the top. Here's a link with some ideas for you:
Here's one I made out of a child desk. Basically you need a framework for your drawers, a base to lift them to a workable height (we built a wood platform with wheels), and a top to work on. Hope mine gives you an idea or two!
There are lots of ideas here on kitchen carts:
Why not add Stone metal Caster wheels and a towel rail at each end. Take the top drawer front off and then either fix it in place or hinge the drawer front back on with a magnetic clasp? The back of the unit could be used for hooks to hold oven mitt or tea towels. Paint up to match decor.
Here is another idea!! On wheels it's fantastic:
Here is how I converted a small dresser into a rolling wine rack. I think it would be similar for a cart.
Build a frame and put on a moving dolly.
