Here are the supplies you will need to create it. I lost my attachment of the scoring blade so I had to improvise with the bone folder.
Well, this was the best way for me to show you what your cardstock shall look like after you have scored all the lines.
First cut your cardstock to 8 3/4" x 7". The picture above may not be so clear with the numbers but the one below is clearer. You may click on each photo to see the numbers better.
After you have gotten all your scored lines done, you will now cut on all of the solid lines.
Now you will fold on all the dashed lines.
Here, you will fold over the flap to create the bottom of the holder.
Another photo to show you I folded the paper over.
Here is what the base of the magazine holder will look like.
Now you can start by adding sticky strip to keep the flaps down and adhere top to bottom.
