Brighten your home with these easy DIY heart string lights.
One of the things I don’t like about living in the UK is the gloomy, grey winter days. To brighten up my home, I made some fun heart string lights to go with the neon string heart decoration I made.
When I was eight years old, I discovered Shrink plastic. I thought it was a fantastic craft and made endless key chains, badges, and bracelets from the stuff. I even experimented with shrinking everyday plastic packaging into fun trinkets.
This used to be great fun with the old-style crisp packets, but unfortunately, it doesn’t work with the new foil packets.
DIY Shrink Plastic Colourful Heart-Shaped Lights
Even many decades later, I still haven’t grown out of my love of crafting with shrink plastic. I have used it recently to make some fun luggage tag pins for a travel-themed map magnetic board. I’ve also used them to make some Christmas illuminated garlands.
Keeping with this theme, I used shrink plastic to make colourful heart shapes for these Valentine’s string light decorations.
This craft is also a great way to find a good use for the copper string lights, you have leftover from your Christmas decorations.

What you need to make heart string lights.
- Clear Shrink plastic – I used two sheets.
- Heart-shaped cookie cutter
- Sharpies or felt tips in pinks, reds & purples
- Copper string lights
- Hot glue gun
How to make heart string lights.
Step 1: First, place the heart-shaped cookie cutter onto a sheet of shrink plastic and draw around it. Then cut out the heart shape.
Cut out as many heart shapes as you want on the string of heart lights.
Step 2: Next, colour your hearts using sharpies in various pinks, reds, and oranges.
For these string lights, I just went for a simple striped design. However, if you want to be more creative decorate your hearts with different designs. You might want to check out my embroidered hearts for more ideas for heart designs and patterns.
Step 3: Next, place the heart shapes on an oven tray and shrink them according to the instructions with your shrink plastic. Mine was at 150c for about 3 mins.
The plastic, as it heats, will curl and then uncurl as it shrinks to about 1/3 of its original size and becomes 6-9 times thicker.
Step 4: Using a glue gun, glue the plastic hearts to the copper wire lights. I twisted the copper wire, so three lights were stuck to the back of each heart.
Step 5: Continue sticking the heart shapes to the copper wire until they are all stuck down. There were about 20 plastic hearts on my string of lights.
Now all you need to do is decide where to hang the string heart lights and plug them in.
These lights make for a lovely, fun Valentine’s decoration. However, you could use different-shaped cookie cutters to make other-shaped string lights.
Also, some plastic packaging can be shrunk like the shrink plastic sheets, so you might want to play around with some of your plastic waste and use that instead for a more eco-friendly craft. I have a great tutorial on how to make shrink plastic earrings and many more Shrinky dink ideas.
