Velcro for Valentines

Since it is Valentine's Day, I was thinking of some type of gear that is romantic in the deep woods. A sleeping bag for two crossed my mind. My wife and I have sleeping bags that we can join together, so we can cuddle under the stars. The only thing I have not done is join our thermarest sleeping pads together to keep them from moving around. One solution I have come up with is velcro. I have not tried it yet, however it seems like it would work. Any suggestions?
