Well, I finally got around to fixing up a "latch" for my sliding cabinet doors. Sorry it took so long, but not a lot of stores carrying velcro here in Baja.
What I did was to glue a piece of the velcro hook side to the cabinet itself and then took about a four inch piece of the pile side and sewed it back on itself with a tight loop so that the door handle would just fit through it. I then removed the door handle and slipped the loop on the handle. Then it was a simple matter of cutting off the end of this piece so it was just long enough to stick itself to the hook piece on the cabinet. This is working well for us and is Baja tested on really bad washboard.
I tried the stick idea, and it worked fine, but I had to use two sticks. One for the inside door and one for the outside and it was a hassle. And then we lost one of the sticks. So, I think this solution will be idiot proof which is a requirement for me....
Plus, if it doesn't work out or I change my mind, it's easy to remove.
