low-poly pineapple wall art

My girlfriend like pineapples, so for her birthday I made her a low-poly pineapple wall art piece.

Finished Product first

Low Poly edit in photoshop

You use the poly-select tool to make triangles, then use the average blur filter on each selection
All done with the low-poly edit

Once you're satisfied with your polygons you can clean up the edges with the eraser tool
Close up of board

3/4" thick 6' by 6" whitewood board cut into 4 equal 15" pieces using a jigsaw
The boards stacked

Just to see if the boards were even, I gave the edges some sanding here with some 220 grit
First board using jacobean stain

I used Minwax Jacobean penetrating stain, I applied it with a 3" brush, just do a thin coat. Make sure to leave the brush in a cup of paint thinner when you're done because stain isn't water soluble.
All 4 boards stained

Make sure to get the edges!
All 4 boards dry

Wait about 15 minutes
Up close after I wiped off the excess stain

Use a clean cloth or paper towel to wipe off the excess stain after about 15 minutes of letting the stain soak in. Let the boards dry over night.
Getting the brackets drilled and screwed (I didn't use the drill to screw the screws)

I flipped the boards over and marked where I needed to drill holes using the brackets. I just found the brackets at Lowe's by the door hinges. I drilled the holes very shallow with a 5/32" bit. Then I used a screw driver to screw in #8 1/2" screws. You drill the holes and use the screw driver to screw them in so you don't split the wood.
All bracketed in

After all the brackets are in place its about time for a clear coat
Getting ready for the first coat of clear coat

Fist coat on

I used Minwax polycrylic protective finish, I used the same 3" brush for this as well. I had to pour it into a bowl because I my brush wouldn't fit in the can. You can pour the excess back in the can when you're done with the first coat.
After the first coat had dried

Once the first coat is dry after about 3 hours give the board a good sanding with 220 grit or higher sandpaper.
After the second coat had dried

I repeated the same process for the first coat and let it dry overnight.
Hangy brackets put on

I hammered the nails into the top corners, the included nails were too long, so I just used some shorter wire nails I had lying around. I think they were 1/2" long.
Pineapple printed and started tracing on Birch Plywood

I used newspaper because I didn't have transfer paper. Push pretty hard with the pen/pencil so the newsprint will transfer to the board. I taped the paper in place so it wouldn't move around. I had my tablet with the picture pulled up for reference if the any lines were hard to see.
All traced out

After I went back over the trace lines

The newsprint didn't leave a very noticeable trace mark so I went back over them with the pencil.
Rough cut out on the ban saw

The Birch Plywood piece was about 3' by 3'. It was too big to work with so I did a rough cutout of the edges so it'd be easier to work with.
Edges cut out and first few pieces cut out

Go slow and use safety goggles. I also recommend using something to hold the wood so you don't have to get your fingers close to the blade.
All the pieces cut out

I placed the pieces down as I cut them out so I wouldn't lose track of where they were supposed to go. I put them on a cookie sheet with that press seal stuff. It's sticky enough to keep them in place, but not so much that you can't move them around if you need to.
Started mixing colors

Painted with acrylics. I bought Red, Green, Blue, Yellow, Black, and White paint. You can follow basic paint mixing tutorials online to get the desired color. I recommend having a color wheel to help you know what to mix to get the desired color. I again had my tablet for reference so I knew what color to make. I got a small mixing pallet and a small paint brush to paint with. Use water to clean your brush, and paper towel to dry it.
This is going to take a while

I sanded the edges of all the pieces before I started painting them with 220 grit sandpaper, and 320 grit on the face of the pieces. Make sure to wipe off all the sawdust before painting. I got the first piece pained, make sure to paint the edges too, especially if the piece is on the edge of the design. Make sure the coat is even.
Small bits of progress

Mixing paint is hard if you're not good at it, this is after an hour. It's a good idea to have scrap pieces of wood for testing colors.
After 2 hours of mixing

This is taking longer than expected. I decided painted the greens since I bought green paint to begin with, it was easier to get the right color.
2 and a half hours

My tablet died so I had to resort to my phone
The next day, lots more progress

To achieve a gold color I recommend mixing yellow with purple(red+blue). Then add bits of yellow, red, blue, purple, black, or white to get the correct color.
All done

All the pieces are painted.
Dry fit before epoxy

Brought it over piece by piece and made sure they look good.
Got the epoxy ready

I mixed a two part epoxy together in a disposable bowl with a disposable knife. The epoxy sets in about five minutes, so I had to do a couple pieces at a time then get squeeze more epoxy out when I ran out.
First few pieces in place

I used masking tape to mark the ones I had glued down
I think it turned out pretty good

After all the pieces were glued down
Close up of the edges

That shine tho
Another angle

I wanted to see it on a wall

It hangs up easily with two small nails in the wall
