Step 4: Drill holes for hinging panels
Once both sides of the five panels have been covered and have dried, you can make the holes down the sides of the panels which will allow you to join them all together.

We used a hand drill to do this, but an electric one would be fine, also. Measure 3" (or 7.5cm) down from the bottom edge of the arch and then 1/4" (or 6mm) in from the sides, then make a mark with a pencil. This will be where you will drill your first hole.

Then make markings for two more holes, 2” (or 5cm) apart, going downwards. You will now have one complete set of markings: i.e. a 3-hole set.

Now measure 7" (or 18cm) down from that last hole to mark the first hole of your second set. Repeat the pattern by marking another hole down 2" (or 5cm) and the last one down another 2" (or 5cm).

Repeat this another two times for your third and fourth sets of holes. You should now have 12 hole markings down one side of panel, i.e. four sets of three holes.

Repeat this procedure on all five panels. Note that the three middle panels will have to be drilled on both sides, while the two end panels will only have holes on one side. Make sure you check on which side you should be marking the two end panels.

At this point, take the time to confirm all your measurements are accurate and double-check before you actually drill the holes. We recommend you place a very thick piece of lumber (or the like) underneath the panel while you are drilling to protect the surroundings. We also used quite a fine drill bit, since the yarn we used to join all the panels together, though very strong, was quite thin.
