And here it is now.
I used the same stencil on the desk that I'm using for my walls. I just taped it to the front of the desk where I wanted my design to go.
I used my plier/wire cutters to cut the strips and then, the most important thing (besides the hammer), is to have a tin punch tool on hand. The way the nailhead strip works is that every few nailheads there is a little hole in the middle and you use an individual nailhead (that comes with the strip) there to secure it to whatever you are using it on. The thing is, when you cut it to the length you need, there isn't always a hole at the end. So the tin punch tool works like a charm to add one. It also helps to make a pre-hole in the wood if the wood you are working on is really hard. The nailheads will bend if you hit them at an angle! Major pain in the butt! Making a pre-hole helps to avoid that.
So there you have it! Easy-peasy!
