Shipping boxes piling up from another round of online shopping? Reuse them to create this 3D cardboard Christmas tree that you can actually decorate and give your home eco-friendly, festive flair.

Print + Prepare Pattern

Print the Cardboard Tree pattern onto card stock (Image 1). Cut away the two smaller "V" shapes from the first page and set them aside. Follow the guide arrows on the pattern pages to tape the tree together and cut it out (Image 2 +3).

Trace + Cut

Trace the tree pattern onto a large piece of cardboard (Image 1). Cut it out with a craft knife (Image 2 +3) and set aside the leftover cardboard. Use scissors to get smoother, rounded edges on each of the branches (Image 4). Repeat this to make six Christmas tree halves (Image 5). Tip: To make the taped pattern fit on one piece of cardboard, you'll need at least a 48" x 16" piece of cardboard. If you don't have a piece that large, you can carefully tape multiple pieces of cardboard together.

Cut Branches

If you haven't already, cut out the "V" shapes from the first page of the pattern (Image 1). Trace them onto the leftover cardboard and cut them out (Image 2). Cut out as many branches as you would like — we used about 35 on our tree (Image 3).

Tape Together Tree Halves

Working vertically, tape two of the tree halves together on one side (Image 1). Then fold one tree half on top of the other and tape the other edge (Image 2). The two tree halves should open and close like a book. Be sure to trim any excess tape. Repeat this process with the rest of the tree halves (Image 3). Tip: You can use any tape for this, but I'm using an industrial strength packing tape made specifically for cardboard.

Insert Branches

Decide where you want each branch to go, then mark the inside and bottom of the "V" with a pencil (Image 1). Then, using a ruler as a guide, cut along the points to create a slit for the branch to slide into (Image 2). Carefully insert the branch to ensure it fits, then adjust the slit if necessary (Image 3). Repeat for all the branches (Image 4). Remove the branches and set aside.

Tape Tree Together

Now assemble the three tree pieces: bring together two taped tree seams, then tape those together (Image 1). You'll have three seams total to tape together.

Cut and Attach Base

Now grab the base template from the last page of the pattern (Image 1). Trace it onto cardboard and cut it out. Measure and cut a 1" x 2" rectangle centered on the bottom of the tree (Image 2). Attach the tree to the base so each tree segment is equally spaced (Image 3).

Paint

Paint your tree any color you like. Be sure to paint the extra branches as well. Let the paint dry overnight. Tip: I used a pale green acrylic paint and a paintbrush, but I'd recommend spray painting as this took forever to paint.

Decorate + Enjoy

Once the paint is dry, put the branches back in place and then trim your tree with a tree skirt, tinsel and lightweight ornaments.
