I am lucky to have a very practical hubby.
He adapted a shelf-system for me and made me a trolly with mostly plywood shelves, but with two drying-shelves made with a rectangle frame with one post across the middle widthwise - and attached wire mesh to them, so that air gets to both the top and the bottom of the pieces. Works great!
As I said, the rest of the shelves are made of plywood. The shelf-system is that the holders have two hooks at the back, and there is then a post (all of this metal) with corresponding holes in it, so that I can change the distances between the shelves.
Only bummer with this trolly is that it almost as tall as the doorways, and I learned the hard way, that putting tall pieces on the top shelf is NOT a good idea! :-(
Also, the wheels are a bit too hard, so that it jiggles a lot being rolled over the tile floors in the basement.
