Step 1: Get The Required Stuff
I then gathered up all the tools and materials I thought I would need.
-Measuring Tape or Yardstick
-Staple Gun & Staples
-Small Shelf Brackets (I got the smallest I could find which were about 3-4 inches per "arm"
-Short screws for attaching brackets to the cornice
-Screws appropriate for use with drywall anchors
Step 2: Measure and Cut
I made lines where I had to cut, and made my cuts.
I clamped down a scrap piece of wood to use as a straight edge to help get straight cuts.
Step 3: Glue and Clamp
This step took a LONG time because I only had 2 clamps. I waited at least 45 minutes before I removed the clamps so I could glue the next part. Just take your time and make sure everything is dry before you remove the clamps.
