Note 1: Use of power tools and spray paint can be dangerous. Use proper safety precautions.
Note 2: Make sure you obtain the cones in a legal manner. Stealing public/private property is illegal.
Step 1: Materials and Tools
String(s) of LED Christmas Tree lights (I used two 60 bulb strings for the larger "tree")
Spray Primer (I used Krylon)
Spray Paint (I used Krylon for this too)
You may also need rubbing alcohol and cotton balls
Note: If the tree is to be displayed outside, make sure the lights and paint are meant for outside use.
A drill and drill bits
A sharp knife
a Sharpie or other marker
You may also need a putty knife and/or pliers
Step 2: Clean It Up
Depending on whether the reflectors are glued on or "welded" on, you will need to remove them in one of the following manners.
1. Glued: Peel off the reflector. A knife might be useful. soak glued area with rubbing alcohol and let it soak in for a couple of minutes. Soak again, and scrape with a putty knife. This will make a mess!!!
2. "Welded": Using a sharp knife, carefully slide the blade between the cone and the reflector, and slice the reflector. Now, peel the reflector from the cone.
Now clean the cone off with warm soapy water or alcohol (you can use both, but not at the same time).
Step 3: Marking
Step 4: Drilling
Once you are sure that you have the right size drill bit, start drilling the holes. The sharper the bit, the better. 120 hole was tiring, but I did it in one sitting. This makes a big mess, so make sure that you drill in a place that is easy to clean.
Step 5: Priming and Painting
Spray several light coats.
Follow the primer's direction on how long to wait before spraying the top coat.
Spray several light coats of spray paint. Make sure the paint is completely dry before moving.
Note: Vinyl and carpet paint (Dupli-color makes one) might work better the normal spray paint.
