I do a fair bit of cooking, and thought it would be nice to have a collection of spices in our trailer, but where to put them?
I built a spice rack custom-built for those little spice tins that you used to find everywhere and built a "magnetic" spice rack that holds the tins in place during transit. I just test-towed the trailer and spice rack on a weekend trip, and everything stayed put. It's cool!
About half my tins came from a close-out sale from a store on Vancouver Island, BC that was clearing out their remaining stock at $0.99 each . . . many of my tins claim to be "poultry seasoning" or "mace;" I emptied them out and I printed large, easy to read labels for all my tins telling me what's really inside. The outer frame of the rack is 1/4" x 1-1/2" stained poplar, the two "shelves" from 5/8" x 1-1/4" scrap wood, so the 2" deep tins actually stick out from the shelves. The magnetic strips at the back are two runs of 1" wide strip-magnets mounted 1/8" up from the tops of the shelves so the lip of the tin can slide under.
Michael's arts & crafts store sells the magnetic tape. It's sold in rolls next to the kid's science supplies: buy the thickest, strongest magnetic tape they sell.
The two shelves are thicker so you can get your fingertips around the tin you want and give it a light
tug. All the interior surfaces are painted white.
