Cardboard Loom Weaving Earth Day Heart
Make a green‑blue woven heart in under 30 minutes.
The cardboard loom heart takes about 25 minutes to finish.
Earth Day calls for simple, sustainable crafts. This loom heart uses recycled cardboard and yarn you likely already have.
All you need is a template, some green and blue yarn, and a quick‑release stick. The result looks like a tiny planet‑loving badge.
You can weave a bright Earth Day heart on a simple cardboard loom in less than half an hour using just yarn, a popsicle stick and a few scissors. Follow these steps and you’ll have a reusable décor piece for the planet.
What you need
Cardboard
Corrugated, at least 12 × 12 in; inexpensive from a box
Yarn
Worst‑weight green and blue; about 50 ft each
Popsicle stick
Plain wood, 4 in long; any craft store sells them
Scissors
Sharp enough to cut cardboard cleanly
What You’ll Need
Gather a sturdy piece of cardboard, two skeins of green and blue worsted yarn, a pair of scissors, a ruler, and a popsicle stick. These items cost under $10 total.
- Cardboard – 12 × 12 in, corrugated
- Green yarn – worsted weight
- Blue yarn – worsted weight
- Popsicle stick – plain wood
- Scissors – sharp
Speed hack: cut all yarn lengths to 2 ft before you start to avoid interruptions.
How to Build the Cardboard Loom
Trace a heart shape onto the cardboard and cut it out with scissors. Use a ruler to keep the lines smooth.
- Heart template – printable or free‑hand
- Cutting depth – 1 mm for easy handling
Speed hack: score the outline first, then cut all the way through for a cleaner edge.
Wrapping the Yarn Around the Loom
Make 1‑cm notches along the top and bottom edges of the heart. Loop the green yarn over each top notch, pull it down to the bottom notch, and leave a short tail.
Speed hack: use a clothespin to hold the yarn tail while you work on the next notch.
Weaving the Heart
Slide the popsicle stick under the bottom notches to keep tension. Pass the blue yarn under one top notch, over the next, alternating across the heart until you reach the opposite side. Keep the weave snug but not stretched.
Speed hack: count two stitches per notch to maintain even spacing.
Finishing and Display
Pull the yarn tight, trim any excess, and slide the completed heart off the stick. Tape the back of the cardboard to a wall or frame it for a quick Earth Day decoration.
Speed hack: use a small piece of double‑sided tape to attach the heart without visible fasteners.
Step
Cut the heart template
Trace a heart onto cardboard and cut it out with scissors, keeping the edges smooth.
Create top and bottom notches
Make 1‑cm notches evenly spaced along the top and bottom edges; these will hold the yarn.
Loop green yarn
Loop green yarn over each top notch, pull it down to the matching bottom notch, and leave a short tail for weaving.
Insert the stick
Slide a popsicle stick under the bottom notches to maintain tension while you weave.
Weave blue yarn
Pass blue yarn under one top notch, over the next, continuing the over‑under pattern across the heart until you reach the opposite side.
Secure and trim
Pull the yarn snug, cut any excess, and gently lift the heart off the stick.
Ways to change it
Paper Loom
Use thick recycled paper instead of cardboard for a lighter, softer feel.
Color Swap
Replace green and blue with autumn reds and browns for a seasonal version.
Size Up
Double the template dimensions for a 12‑inch heart; use bulky yarn and a longer stick.
The short version
- The loom heart can be completed in about 25 minutes.
- Only three tools are required: cardboard, yarn, and a popsicle stick.
- Green and blue yarn give the Earth Day palette, but any colors work.
- If the yarn slides, tighten the stick or add a second stick for extra tension.
- Trim excess yarn before removing the heart to keep edges neat.
Questions people ask
What if my yarn keeps slipping off the loom?
Make sure the notches are deep enough and press the stick firmly; adding a second stick on the opposite side creates more grip.
Can I use thicker yarn?
Yes, just widen the notches and use a sturdier stick; the finished heart will be larger but still stable.
