How to Recycle Sweaters into a Heart Decoration

Recycle Sweaters For Valentine’s

After the annual New Years purge of my wardrobe, my pile of recycling sweaters has grown. I’ve got big upcycle project planned for a lot of the sweaters. But this little stripy jumper, unfortunately, didn’t make the cut. However, I did manage to recycle the sweater into a cute heart decoration.
Valentine’s day is actually my birthday and this year it’s a big one! I thought it would be fun to decorate my home with lots of hearts. I’ve already had fun making some heart string lights. Now I’ve got the sweater felt heart to add to the decor and there is more on the way!
This is a really simple sweet craft that can be completed in under an hour and costs virtually nothing to make. It’s so simple that you could even do it with the kids.

What I used to recycle sweaters into a Heart



How to Recycle Sweaters into a Heart Decoration

  1. Firstly I bent the wire coat hanger into a heart shape and used the wire cutters to cut the hook off.


  3. Next I felted the sweater by putting it in a hotwash like I did with my sweater mountain cushion. Once felted I cut of the sleeves and put them to one side for another project.

  4. For the next stage, I cut the sweater up like you would cut a t-shirt to make t-shirt yarn. This is difficult to explain how I did that in words, however there are some great info graphics on pinterest that show exactly how to do it. Like this one here.

  5. To ensure I cut felted sweater yarn of an even thickness, I used a rotary cutter, board and metal ruler.

  7. Finaly to make the heart decoration out of the sweater felt. I simply wound the felted yarn around the coat hanger heart, using a hot glue gun to stick it to the wire. I covered the heart in a random criss cross pattern.

Don’t throw away the unused recycled sweater sleeves, you can use them to make an upcycled sweater felt garland.

  1. Clever idea, and a cute heart. Love the sweater garland!

  2. Oh such pretty things to make from something too many people would just throw away – love them! Thank you for once again joining in with #GoingGreen and I hope you can link up again when the next one opens on March 5th

  3. Such a good idea! I’ve never tried cutting up a sweater and using it in a craft, but your idea turned out so nice I may give it a try! Thank you for sharing on Party in Your PJs.

    • Thank you. If you felt a sweater it’s great for cutting up and using in crafts as unlike other fabrics it doesn’t fray.

  5. You are so good at this Claire and it’s always a treat to see your new creations. Our second oldest son’s birthday is Valentine’s Day also. Best Valentine’s gift ever! Thanks for joining us at Celebrate Your Story.

    • Thank you, Sandra. There are quite a few February birthdays in my family, and my best friend at School shared a Valentines birthday with me.

  6. I love this Claire!! You make the most amazing things!! I have one sweater I could do this with, I may have to give it a go 🙂

    • Thank you Debra. I love to think of new ways to upcycle old sweaters, I’m currently working on a rug!

  10. I KNEW this was you just from the little picture in the link up box!! I love your tutorials Claire — this one is fabulous! Thanks ever so much for sharing #HomeEtc

  11. What a nifty idea and you are recycling too!! I suppose you liked the ‘T’ and to see it in another shape, is better than using it as a scrub!

  12. very, very clever! How did you think up this?!

    • Thank you, Wendy. My brain is just stuffed full of craft ideas but not much else at the moment.

  13. This is a great post. I love how you make something usable and cute out of castoffs. What a wonderful idea. Happy Birthday… well in a couple of weeks anyway.

    • Thank you, Leanna. And thanks for the Birthday wishes in advance.

  14. Another super cute felted wool idea Claire. I’ve run out of felted wool for a while (I need another trip to the charity shop) but I can see this working well with t shirt yarn too.

    • Thanks. Lucky for me my mum just gave me another stash of her old cashmere jumpers. This would work just as well with t-shirt yarn though as it doesn’t fray.

  15. What a creative upcyle! Your sweater heart wreath looks great! Thanks for sharing at Snickerdoodle! Pinning.

  16. Your textile crafts are so creative! Thanks for sharing at Vintage Charm!

  17. Another fabulous project, Claire! No wool sweaters around here, maybe need to try the thrift store, or just stick to my sheets and linens! You could cut those sweater sleeves in a spiral to make more yarn, yes a lot of seams but good to think about in case the body of the sweater doesn’t give you enough. Thanks for sharing on craft schooling Sunday as always!

    • Thank you Sara, t-shirt yarn would work really well as it won’t fray.

  18. It’s another winner Claire. Love the look of the sweater heart and how easy it was to make. I do hope you have a very happy, special birthday in a few weeks time and can’t wait to see what else you have up your sleeve 😉

    • Thank you, Michelle. I wasn’t looking forward to the mile stone coming up at first but have now decided that the best thing to do is just embrace it and enjoy it.

  19. I love your crafts and your instructions are so clear and ‘do-able’!

  20. Claire, this is so cool! I love all the projects you make from clothing. I need to get one of those cutters and mats, they make perfect lines so much easier. Making the sweater into “yarn” worked great on your cute Valentine heart <3

    • Thank you, Toni. Rotary cutters and a mat are handy for so many crafts, great for cutting both fabric and paper.

  21. Super cute! What a fun project for Valentines Day!

  22. What a clever recycle, makes the most of this stripy sweater.

    • Thank you, Amalia. Yes the stripy sweater was perfect for this particular craft.

  23. I so look forward to your posts every week Claire to see what your latest creation is. Love this idea for Valentine’s and Happy Birthday in advance! X #HomeEtc

    • Ahh, thank you Lins. That is nice to hear. I just love crafting and upcycling there is plenty more to come.

  24. Your DIYs never fail to amaze me! So clever and so well done!

  25. Another great upcycling project, Claire! I love it!

  26. I love this. Sooooooo cute.

  27. Super cute and creative, as usual! Love the wire poking through.
