All you need is an edge punch that will work for the lacing and some designer paper or cardstock. I've used some Brown Kraft and Buff Ivory cardstocks so you can see the details easily. I can't really give you any measurements because it will depend upon the size of your project and the width you decide you want between the panel edges.
For this card I cut a panel of the Brown kraft 5.5" x 11" and punched one short edge. I trimmed it off at about 1.25" so I'd have some play room. It was trimmed smaller later. Taking the larger leftover pieces of Brown kraft I repeated the punched edge. After that it's just a matter of figuring how much to trim off your pieces.
You will get different looks depending upon what type of edge punch you use. I was going to use the same one Gerry used in her tutorial but broke the punch. grrrrrrrrr
Anyway, here's what the finished card looks like with the panels laced with some Earthy hemp cord and a Scalloped Grungy Prim tag sentiment.
Hope you'll give it a try. It's really simple and gives a great decorative element to your project.
