In Which The Laundry Cabinetry is Completed (At Last)

It's been nearly a year since the laundry closet was pressed into service, and it's worked perfectly for our needs thus far. That said, I never really finished the cabinetry and trim, especially the tall base cabinet on the right. The wife finally got sick of looking at the exposed framing and requested that I get around to finish what I started.
There are two similar profiles used on the cabinet and door moldings in the house. The doors in the older parts of the house have a 3 step profile with squared edges, very empire-esque. The overlay cabinetry in the newer parts of the house have a very similar profile, but with slightly more rounded edges (see below).

Truthfully, I really don't want to have to mill trim if I can help it, and any kind of cabinet door would require molding. Drawers would be one way around making molding, but I need the vertical storage for tall bottles of detergent and tall drawers would look strange. I would also have to make either choice overlay, which wouldn't really look right with the rest of the laundry cabinet. Then, I had the idea to use a backset tambour door.
Apart from the inconvenient little fact that making a tambour is probably more work than a rail and stile panel door, it sounded like the perfect solution! I remembered seeing tambour door kits online, but a quick google search showed that for the size I wanted, I would be looking at $100+ for veneered MDF without rails. And all these newfangled tambours use spring-wound spools or spiraled tracks instead of just wrapping the tambour around the back of the case. Whatever, it's not like making one is particularly hard.
After a bit of waffling, I settled on 1/4" poplar for the door material, and aluminium bar for the rails. I used some canvas tarp as the backing and Super 77 as the glue. The glueup was a bit of a mess (read RPITA), but it turned out nicely. The contrast between the sap and heart wood of the poplar looks sophisticated and almost like I did it on purpose.

The idea was to paint it with the standard trim enamel, but we both like the way it looks natural.

 Like Magic!
Sort of... it is a lot smoother than I would have expected, but the fit isn't perfect. Still, once I decide on a finish for the door, I'll have finally completed building the cabinets for the laundry closet.
