1 Box with the width and height you want
Fabric to cover
We removed the clear packing tape from the bottom of the box so it could be laid flat.
We measured my stair height (approx. 8 inches) and depth (approx. 12 inches). Using a long metal ruler we drew straight lines on the box to identify where the 'step' piece would be. Do this on both sides of the box..be sure to work on the same end :)
Here is a bit of a tricky part, I only made 3 cuts on each side of the box (see picture below - I made cuts along the bold black lines and I folded along the dotted line) so that I could fold the box and keep most of the box intact to create the bottom and side of the 'step' part.
I removed the top flaps of the box because I did not need any extra height. If you box is not high enough, you can use the top flaps for this.
Making the shape of the stair basket, took me about 10 minutes to do. But the next step of covering it with fabric took me almost 2 hours! I didn't have much of this fabric left over from recovering my kitchen chairs so I had to plan wisely. It really wasn't difficult as I used Mod Podge to secure the fabric to the box but the planning took me forever. I used some left over black vinyl for the bottom of the box so that it wouldn't show any dirt (plus I didn't want to use more of the fabric since I might want to use it on something else later).
