I was going to use contact cement to adhere the fabric. Wanted to get a good seal on it. However, that stuff turns the fabric orange/yellow and that just wasn't going to work. So had to use Mod Podge. Not as good a seal but with enough of it applied to the top it should hold.
Next.... I started applying the fabric in the back by doing one section at a time. Quickly found out how hard it was to line up the pattern. Then had a "Duh" moment. Started at the top and applied the glue. Then laid the entire piece of fabric down so that it draped over the edges. Smoothed out all the edges on the top and then applied the glue and worked my way down both front and back. Did the same to sides. Then, when it was completely dried it used an x-acto knife to cut everything out.
Now for the last and should be most obvious bit of advice. Change the blade in the x-acto knife often!!! Don't know why but that's something I have hardly ever done. I just keep plugging along with a dull knife. LOL That not only makes a mess of the edges on the fabric but the only times I ever nicked myself with that knife was when it was dull. Know about this rule when cooking but just never gave it much thought toward these sort of things. I mean, those x-acto knives are supposed to stay sharp forever right??
